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)

first option
