Answer 1

*Find the OPEN intervals on which if is decreasing, rather.

Answer 2

its going to be when the slope is negative

Answer 3

Answer 4

The critical points are at x=0 and x=4 i believe

Answer 5

i agree so the question is whats the slope before and after zero
and
what is the slope before and after 4
