1. Go Gryffindor! Inverses

2. Inverses The inverse of a function is the function flipped about the line y=x

3. The red graph shows the inverse to the blue graph (the dotted green line shows the line y=x)

4. To find the inverse of a function You switch the variables x and y Then you solve for y

5. When solving for an inverse Make sure to remember plus and minuses When you find a function’s inverse often the resulting graph is not a function so you must remember all of the parts of the graph
