[im the confusion]
use composition to determine if g(x) or h(x) is the inverse of f(x) across the
domain x2 -7.
f(x) = x+7
g(x) = (x-7)
h(x)= x2 +7

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
