3.07 Vertex Form of Quadratic Functions
Part 1
Answer questions 1-4. For each function, identify the vertex, domain, range, and axis of
symmetry. Answer yes or no to whether there is a vertical stretch, vertical compression, or
reflection over the x-axis. Then, choose the correct graph for each function from the choices
below. You will not use all of the graphs.
