11-29.

For each function, find the inverse function.

1. $f(x)=\frac{x}{3}−2$

List the steps for this function.
1) Divide by $3$.
2) Subtract $2$.

Change each step to its inverse operation.
1) Multiply by $3$.
2) Add $2$.

Reverse the order of the steps.
1) Add $2$.
2) Multiply by $3$.

Write an inverse equation for the new steps.

$f^1(x)=3(x+2)$

1. $g(x)=\frac{1}{2}x+5$

Follow the steps in part (a).
