2-14-24 Quadratic Notes

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

• Vertex Form

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

• Standard Form

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

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

• Intercept Form

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

• Vertical Compression

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

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.
