f%28x%29=abs%28x%29-10
g%28x%29=2x%5E3
(g o f)%28-2%29
(g o f)%28x%29=g%28f%28x%29%29
(g o f)%28x%29=g%28abs%28x%29-10%29

(g o f)%28x%29=2%28abs%28x%29-10%29%5E3...use %28a-b%29%5E3=a%5E3-3a%5E2b%2B3ab%5E2-b%5E3
(g o f)%28x%29=+2abs%28x%29%5E3-60abs%28x%29%5E2%2B600abs%28x%29-2000

now find (g o f)%28-2%29
(g o f)%28-2%29=+2abs%28-2%29%5E3-60abs%28-2%29%5E2%2B600abs%28-2%29-2000
(g o f)%28-2%29=+-1024

                     f(x) = |3x| - 10
f(- 2) = 6 - 10 = - 4
