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!

Answer:

Step-by-step explanation:

Lines have angles that are equal to 180. Therefore, because we already have 140 of the 180 necessary, we can subtract 140 from 180 to get 40. 40 divided by 5 is 8.

Hope that this helps!
