1. Consider the key features discussed in this lesson for the four graphs of quadratic functions below.
(Key features include: x-intercepts, y-intercept, line of symmetry, vertex, leading coefficient,
increasing/decreasing intervals, and end-behavior)

2. Is it possible for the graphs of two DIFFERENT quadratic functions to each have x = 3 as its line of
symmetry and both have a maximum at y = 5? Explain and support your answer with a sketch of the
graphs.
