Warm-Up/Review:

1. Graph the function y = 5x2 - 1

Warm-Up/Review:

Find the axis of symmetry for the graph y = 3x2 + 6x + 4a. y = -1 b. x = 1 c. x = -1 d. y = 1

A graph of a quadratic function has x intercepts of (3,0) and (-7,0). Which of the following could match the graph?

a. x2 + 4x - 21 = 0 b. x2 - 10x - 21 = 0

c. x2 + 10x + 21 = 0 d. x2 - 4x + 21 = 0
