Step-by-step explanation:

Step 1: Define

f(x) = 3x + 10

g(x) = x - 2

f(-10) is x = -10

Find g(f(-10))

Step 2: Solve:

Find f(-10). Substitute:                         f(-10) = 3(-10) + 10Multiply:                                               f(-10) = -30 + 10Add:                                                     f(-10) = -20Substitute:                                           g(-20) = -20 - 2Subtract:                                              g(-20) = -22
