Show that the function g(x)=x-2/5 is the inverse of f(x)=5x+2 Step 1: the function notation f(x) can be written as a variable in an equation. Is that variable x or y?

Write f(x)=5x+2 as an equation with the variable you chose above.

Step 2: switch the variables in the equation from Step 1. Then solve for y. Show your work.

Step 3: Find the inverse of g(x)= x-2/5. What does this tell you about the relationship between f(x)=5x+2 and g(x)? Show your work.
