In Try This 1 you had a chance to view many different graphs of quadratic functions. You may have noticed that the graph of a quadratic function is always a particular shape, called a parabola. In the photo shown, the thickest blue line can be described as having a parabolic shape. Can you see the similarity between the thick blue line and the graphs of quadratic functions you have observed so far in this lesson?

This is a play button that opens Axis of Symmetry.

In Axis of Symmetry you will explore the shape of the parabola and its special features.
