Answer:

f(-2) = 26

Step-by-step explanation:

By substituting -2 into the equation, we get

f(-2) = -(-2)^3 + 3(-2)^2 - 15(-2) - 24

Each of the parts can get simplified.

f(-2) = 8 + 12 + 30 - 24

Add and subtract everything.

f(-2) = 26

Hope this helps!

LekaFEV [45]

Answer:

h = 3

Step-by-step explanation:

-8 + 3h = 1

Add 8 to both sides.

3h = 1 + 8

Add 1 and 8 to get 9.

3h = 9

Divide both sides by 3.

h = $\frac{9}{3}$

Divide 9 by 3 to get 3.

h = 3
