## Reflection: Self-Talk Finding the Inverse of a Function Day 1 of 2 - Section 4: Finding equations for inverses

Many students do not understand that when we switch the x and y to find the inverse the x and y have now become different. In some ways the switching of the variables is not precise for many students. It may be better process to solve the original function for x and then state that x=f^(-1) and y=x for the inverse function.

I will move to this process in the next lesson and hopefully this will help students understand that the domain and range are different for the function and its inverse.
