8.02 Combining functions

Given the following values:

$f\left(2\right)=4$f(2)=4, $f\left(5\right)=10$f(5)=10, $f\left(9\right)=18$f(9)=18, $f\left(6\right)=12$f(6)=12

$g\left(2\right)=8$g(2)=8, $g\left(5\right)=20$g(5)=20, $g\left(9\right)=36$g(9)=36, $g\left(6\right)=24$g(6)=24

Let $f\left(x\right)=x^2-1$f(x)=x2−1 and $g\left(x\right)=5x-1$g(x)=5x−1.

Let $f\left(x\right)=x^2+6$f(x)=x2+6 and $g\left(x\right)=5x-3$g(x)=5x−3.
