The graph of y = -x² - x + 6 is shown. Identify each of its solutions.

• -3

• -2

• 0

• 2

• 3

A relationship between x and y is shown in this table. Which equation fits with the data?

• f(x) = 4x² + 4

• f(x) = -4x² - 4

• f(x) = 4x² - 4

• f(x) = -4x² + 4

Solve Using the Quadratic Formula

x² + 4x - 40 = -8

• x = -10 and x = -4

• x = -4 and x = 10

• x = -8 and x = 4

• x = -4 and x = 8
