Graphing Quadratics

y = x² - 2x - 8

Axis of Symmetry?

• x = 1

• x = 2

• x = 8

• x = -2

y = x² - 2x - 8

Minimum or Maximum?

• Max

  y = 8

• Min

  y = -8

• Max

  y = 9

• Min

  y = -9

y = x² - 2x - 8

Vertex?

• (-1,-9)

• (1,-9)

• (-2,-8)

• (2,-8)

y = x² - 2x - 8

Vertex Form?

• y = (x - 1)² - 9

• y = (x + 1)² - 9

• y = (x - 2)² - 8

• y = (x + 2)² - 8

y = x² - 2x - 8

x-Intercepts?

Pick all that are correct.

• (-2,0)

• (4,0)

• (-2,4)

• (-8,-2)

y = x² - 2x - 8

Intercept Form?

• y = (x + 2)(x - 4)

• y = (x - 2)(x + 4)

• y = (x + 4)(x - 2)

• y = (x + 8)(x + 2)

y = x² - 2x - 8

y-Intercept?

• (0,-2)

• (-2,0)

• (0,-8)

• (-8,0)

y = x² - 2x - 8
