Question

Which of the following expressions is the inverse of the function y equals quantity x minus 2 divided by 3

Answer 1

`y=(x-2)/(3)\ \ \ \ |change\ x\to y\ and\ y\to x\\\\x=(y-2)/(3)\to(y-2)/(3)=x\ \ \ \ |multiply\ both\ sides\ by\ 3\\\\y-2=3x\ \ \ \ |add\ 2\ to\ both\ sides\\\\\boxed{y=3x+2}\leftarrow answer`
