If A is less than zero than zero, then AX coins. Great than or equal to 0A TREE is greater than less than equal to zero. 1 Comment / Default / By huanggs Function f (x) = x³-ax is a sufficient condition of increasing the function on the R.

Joann December 1, 2022 at 12:52 pm f (x) = 3x^2-a is the increase function on R, then f (x)> = 0 Heng Establish and the minimum value of f (x) is f (0) =- a So there is -a> = 0 Reply

Joannf (x) = 3x^2-a

is the increase function on R, then f (x)> = 0 Heng Establish

and the minimum value of f (x) is f (0) =- a

So there is -a> = 0
