What is the axis of symmetry of the function y 2x 4x 1?

The axis of symmetry is x=-1

Axis of symmetry formula: x=b -2a

Extended information: In general, a function of the form (a, b, c is constant) is called a quadratic function, where a is called the quadratic coefficient, b is the coefficient of the primary term, and c is the constant term. x is the independent variable and y is the dependent variable. The highest number of independent variables to the right of the equal sign is 2.

Vertex coordinates. The intersection formula is (only for parabolas that have an intersection with the x-axis), and the coordinates of the intersection with the x-axis are and .

Note: "variable" is different from "unknown", and it cannot be said that "a quadratic function is a polynomial function with the highest degree of unknowns being quadratic". "Unknown" is just a number (the specific value is unknown, but only one value is taken), and "variable" can be arbitrarily taken within a certain range.

The concept of "unknowns" is applied to equations (in functional equations and differential equations, it is an unknown function, but whether it is an unknown number or an unknown function, it generally represents a number or function - special cases are also encountered), but the letters in the function represent variables, and the meaning is different. The difference between the two can also be seen in the definition of the function.

The axis of symmetry of the function y=ax 2+bx+c is x=-b 2aSo the axis of symmetry of the function is x=-1

y=x +2, which is a quadratic function, its image is a parabola, and its axis of symmetry is y, denoted as: x=0

The axis of symmetry is the y-axis, with vertices (0,2) and openings pointing upwards.

The axis of symmetry is the y-axis.

For example, y=ax 2+c, the symmetry axis of this form of quadratic function is the y-axis.

Hello, y is equal to x squared plus two.

The axis of symmetry is x equal to zero.

You can make an image where y is equal to x, and then because y is equal to the square of x, no matter how many y's die, it is greater than or equal to zero. Say that your avatar is always in the first and second quadrants, and after adding two, the overall upward movement of the graph line is still in the first and second quadrants, and the image is symmetrical with respect to the y-axis.

Once the term is zero, so the axis of symmetry is x=0

x 0 we might as well make y x , then the axis of symmetry x 0, and then translate the equation upwards by two units of quantity to get the original equation, at this time the axis of symmetry does not change, so the axis of symmetry of the original equation is x 0

y-axis or x 0To apply the formula, the axis of symmetry is equal to b 2a

What is the axis of symmetry of y=x +2?

y= x^2 +2

x-0)^2 +2

Axis of Symmetry : x=0

Summary. Hello, the axis of symmetry of y=-3x -5x+1, calculated as follows:

Axis of symmetry of y=-3x -5x+1.

Hello, the axis of symmetry of y=-3x -5x+1, calculated as follows:

The symmetry axis of the parabola can be calculated using the formula -b 2a, so the substitution data is: -(5 2 (-3)) 5 6

Summary. The axis of symmetry x = b of minus 2a, and the quadratic function is generally y=ax 2+bx+cy=5+x 4x.

If you don't ask enough questions, you can close the order and continue the consultation. I'll send you the information you need, about 3 minutes! Have a great day!

Have a good mood every day ahead!

Hello, the axis of symmetry of a quadratic function can be calculated with a formula.

The axis of symmetry x = b of minus 2a, and the quadratic function is generally y=ax 2+bx+c, so its axis of symmetry x = one-eighth.

The formula for the axis of symmetry in the function is Zheng Song—b 2a

First go to the brackets, the Zheng constant before the second closing loss is a, and the first time the constant is b, and then bring in the above formula, as shown in the following figure.

The axis of symmetry of the function y=6(x+1) is the straight line x=-1

The axis of symmetry of the second letter Luzhou is x=-b 2a;

Because, b=0;x=0

Therefore, the symmetrical early nucleus shield axis is the y-axis.

Function y=(1-3x) (2+x).

3+[7/（2+x)]

So the center of symmetry is (-2,-3),8, and the function y=(1-3x) (2+x)=-3+[7 (2+x)].

So the center of symmetry is (-2,-3),2,
