Question

what is the inverse function for f(x)=5-2x/3 ?

Answer 1

Is it

(5-2x)/3

or

5 - 2x/3

?

Answer 2

\(\bf f(x) ={\color{red}{ y}}= 5-\cfrac{2{\color{blue}{ x}}}{3}\qquad inverse\implies {\color{blue}{ x}}= 5-\cfrac{2{\color{red}{ y}}}{3}\)

solve for "y"
notice to find the inverse relation, all we do is swap about the variables
