The function is increasing for all real values of x
where
6 The function is decreasing for all real values of x
where
<<_6 and where x>-2
The function is decreasing for all real values of a
where
X<-4

First.

Step-by-step explanation:

Expand

f(x)=-x²-8x-12

take derivitive

f'(x)=-2x-8

zero at x=-4

in x<-4, the derivitive is positive so the function is increasing

in x>-4, the derivitive is negative so the function is decreasing

increasing in (-infinity,-4)

decreasing in (-4,infinity)
