Asap! 70 points 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. (2 points) 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.
