The friend information on your ** is aggregated at one time, making ** richer and more cool.

At the same time, in the album and interactive module of the tagged user, there will also be a special "I am tagged**" album to display the photos of the user circled in other people's albums, and other users can also click on their ** to directly enter the photo owner space when browsing. A photo of you and all your friends in one place.

f'(x)=(a x)+1=(x+a) xf(x) increases monotonically on [2,3], so the derivative function f'(x)=(x+a) x is greater than zero on [2,3], i.e., (x+a) x 0

And x>0

So, just (x+a) 0

a≥-x x∈[2,3]

This is an Evergrande problem, which means that the a on the left is greater than the maximum value of the function g(x) = - x on the right.

And the function g(x)=-x is a subtraction function on [2,3], so g(x)max=g(2)=-2

a≥g(x)max=-2

a∈[-2,+∞

Negative A is greater than or equal to the maximum value of Negative X, which is greater than or equal to Negative 2
