This Parametric-Inverses: Graph Matching interactive also includes:
Perform a switch to find the inverse of a parametric equation. Pupils match four parametric functions with the graph of the their inverses. Using the graphs, learners determine whether particular points are on the original parametric function or its inverse. Class members discuss why it is easier to determine the inverse of a parametric equation over an otherwise defined function.
