Curated and Reviewed by Lesson Planet

Reverse the wrapping to get to the gift. Using the idea of unwrapping a gift, the lesson introduces the concept of inverses. Pupils first determine the order needed to evaluate a function at a point, then use the reverse to find the inverse of the function. They graph the function and the inverse and compare the domains and ranges.
