You have worked with three forms of quadratic functions. Think about them and answer the following questions in 1. What are the different forms? 2. For each of the three forms, when would it be most convenient to have the function in that form? 3. Create a quadratic function in one of the forms and show how to convert it to another one of the three forms.
