Question

f(x)=24x^3-94^4-11 find intervals of increasing and decreasing.

Answer 1

we are given

Firstly, we will find derivative

now, we can set it to 0

and then we can solve for x

we get

now, we can draw number line

and locate 0 and 0.255

and then we can check sign of derivative on each intervals

Increasing intervals:

Decreasing interval:
