Answers:

1st box: -2

2nd box: 6

==================================================

Step-by-step explanation:

To find the x intercepts, we replace f(x) with 0 and solve for x.

f(x) = -(x+1)(x-3)(x+2)

0 = -(x+1)(x-3)(x+2)

-(x+1)(x-3)(x+2) = 0

x+1 = 0 or x-3 = 0 or x+2 = 0

x = -1 or x = 3 or x = -2

-------------

To find the y intercept, we plug in x = 0 and simplify.

f(x) = -(x+1)(x-3)(x+2)

f(0) = -(0+1)(0-3)(0+2)

f(0) = -1*(-3)*(2)

f(0) = 6

We can confirm these answers with a graph. See below. I used GeoGebra, but Desmos is another good option.
