Big brothers and sisters, uncles and aunts, what should I do?

First of all, I want to know how old you are, if you are of school age, I personally think that it is still important to focus on academics, and the topic of early love is actually a cliché, but it is still necessary to prioritize. Isn't it, brother? Regardless of your current age, it mainly depends on whether you still truly love each other.

How many times do you value her or do you love her more? You have to know this in your heart, and the second is whether the other party also depends on you and loves you very much. There is no right or wrong in love.

Only who loves a little more than whom. Mindset is very important, and I think whether you are a student or already in the workforce, you should prioritize it. I hope it will help you, and may a lover eventually become a family.

The first time is not for you! Your purpose is not to marry her! If you feel a need......Just keep associating.

Summary. Dear, hello, I'm glad to answer for you, I just was called big brother by my aunt and uncle to see your elder. Some people are called uncles and aunts, thinking that they are saying that they are old. Therefore, people are now accustomed to calling people in their forties and fifties as big brothers and sisters.

Qin Zhen Mu Chong, hello, I am happy to answer for you, Gang Nai Xiang was just called the eldest brother by the aunt and uncle is to see you elder. Some people are called uncles and aunts, thinking that they are saying that they are old. Therefore, people are now accustomed to calling people in their forties and fifties the title of Brother Yu and Elder Sister.

I'm only 21 years old.

2. Delay and refuse to carry the law. You can use the excuse to say that your mobile phone is in arrears or out of battery, and you can't add friends to each other for the time being, and you will have the opportunity to add WeChat in the future. Although this reason is a bit far-fetched, the other party will understand what he means at this time.

This will also prevent the scene from becoming very embarrassing. 3. Euphemistically refuse to politely indicate that you don't use WeChat much, or don't use WeChat to chat much, and apologize in time. In this way, the other party will immediately understand what he means, and it will also show his own politeness.

No, it's just that the landlord aunt calls me big brother.

There's also an uncle who calls me big brother, am I that old?

Dear, it's probably a joke with you, or maybe it's her mantra.

It's just that my beard can't be shaved cleanly.

The beard is a bit thick.

Hello dear, that is, your appearance makes people look older.

To solve this kind of problem, it is recommended that you connect with the knowledge points you have learned and how you proved it in the first place, and it will be much easier to do.

For this problem, the operation that should come to mind should be logarithmic operation.

Let's talk about the process of explaining the questions.

For the first question, we first need to calculate f(1).

By definition, f(1) = f(1) + f(1), so f(1) = 0

There are two ways of thinking in the following calculation, the first is to move the definition to the left by one item, and a negative sign will appear. Another way of thinking is to make it up, which is more practical, but it is not easy for beginners to master. Let's briefly introduce each one.

1) Since f(x1x2) = f(x1) + f(x2), f(x1) = f(x1x2)-f(x2).

Then f(1 x) = f(1)-f(x) = -f(x).

2) Since f(x1x2) = f(x1) + f(x2), so f(1) = f(1 x) + f(x), after simplification, the result can be obtained.

The problem-solving process of the two ideas looks similar, but in the process of solving the problem, they think from different angles, I hope it will help you.

Here's the proof of the even function.

The proof of even functions is much simpler. First of all, according to the method of calculating f(1), let x1=-1 and x2=-1 respectively, and f(-1)=0 can be obtained

In addition, let x1=-1 and x2=x, and then we can get that this function is an even function according to the definition of the even function.

Second, if you think about a function that satisfies these conditions, it should be roughly a logarithmic function in the first place, and that's fine. However, it must also be an even function, which is defined on the negative half axis so the absolute value should be added to x, and in order to meet all the conditions, add a few parameters and it is OK, and the final answer should be.

f（x）=b*log(a)|x|

where b is not equal to 0, and a > 0 and not equal to 1

Hope it helps.

Let x1=x2=1, then we get:

f(1)=f(1)+f(1)

i.e. f(1)=0

Then let x1 = x, x2 = 1 x, then we get:

f(1)=f(x)+f(1/x)

i.e. f(1 x) = -f(x).

Let x1=x2=-1 again, then we get:

f(1)=f(-1)+f(-1)

i.e. f(1)=0

Let x2=-1 again, then we get:

f(-x1)=f(x1)+f(-1)

i.e. f(x) is an even function.

2)、f(x)=c*ln|x|That is, the condition is satisfied, and c is an arbitrary constant.

I think your father's thinking is still very traditional, and some of the ideas of the new students are relatively unfamiliar, but your father also has his plans, in your opinion, he does not know (understand), in short, he is for the good of his own children, you should understand him, but on the other hand, your object, whether to go or not this idea is still for you to take. I suggest you go for ,。。 Don't leave regrets for the rest of your life.

I wish you all happiness.

It is recommended that you go, and then leave a letter explaining what you mean, so that the old people at home have a bottom in their hearts, otherwise you will have to be awkward for a while when you come back.

Xiaohong returned to school to get her books, and met her sister a kilometer away from the school. Xiaohong walked a kilometer more than her sister.

The time they met was minutes.

Xiaohong's home is 1 12*km away from the school.

Kilometer. Little pot friend, do you want to help you calculate it, and finally, don't forget to choose me as a satisfactory answer. You have to repay the kindness......

<> steps are more detailed, I hope it can really help you.

Hahaha, I won't be one.

Congratulations on the New Year: auspicious and happy. Respectfully congratulate you on a happy and auspicious New Year. Phrases used for Chinese New Year.

Satisfactory describes being satisfied, and things are going exactly as they want.

Auspicious Ruyi Xiang: auspicious. Wishful thinking. Use it to bless others with happiness.

Lucky Star Lucky Star: An auspicious star. Describe people as lucky, blessed Jingxing Qingyun Qingyun: Five-colored clouds, symbolizing auspiciousness. The metaphor of auspicious signs is very auspicious and smooth. In the old days, it was used for divination and blessings.

Spring is often in the four seasons of the year, thousands of purples and thousands of reds bloom forever Horizontal batch: welcome the new year.

Isn't there a hint? m2-1=0, and m is not equal to 1, so m=-1

Substituting y=-4
