Lesson Summary: By the end of this lesson, students should be able to find the inverse of a function given the equation, utilizing Esc to remember the steps. First, one should exchange x and y, then solve for y, and finally change y to (f^-1(x)). Furthermore, one should be able to find the inverse function given the graph of the inverse function by using on of two methods: reflecting the original function across y=x or finding a few points on the original function and switching x and y to find he inverse points then graphing them. Lastly, one should be able to utilize (f(f^-1(x))=x to prove that two functions are inverses of each other.
