2. Consider the function 2/5x - 4

Question

a.) Find the inverse of f(x) and name it g(x). Show and explain your work.
b.) Use composition to show that f(x) and g(x) are inverses of each other

Answer 1

The procedure for determining the inverse of a function is well known (interchange y & x, then solve for new y).

 

Just follow instructions. But be sure you know exactly what the function is (we do not...see Mark's comment).
