P4 A-C, E. Match the questions to their answers.

• What does this quantity tell you about the graph of the function?

• Vertex Form

• Which form would you use to determine the x-intercepts of the graph of the function?

• Vertical Compression

• Which form would you use to determine the minimum value of the function?

• Intercept Form

• Which form would you use to determine the y-intercept of the graph of the function?

• Standard Form

• Do the function rules for each form have any single quantity in common?

P4 D. Match the following key characteristic of the graph that can be determined only by looking at the corresponding form of the quadratic function.
