Working Together Take turns to match a function to its graph. As you do this, label the graph to show the intercepts on the x- and y-axes. If you match two cards, explain how you came to your decision. If you don't agree or understand, ask your partner to explain their reasoning. You all need to agree on and explain the matching of every card. You may find that more than one function will fit some graphs! If you have functions left over, sketch graphs on the blank cards to match these functions.
