• 2

• 7

• 0

• -3.5

• 3.5

Match the following.

• Standard Form

• Vertex Form

• Intercept Form

• (-3, 4); x = 4

• (3, 4); x = 3

• (-3, 4); x = -3

• (4, -3); x = -3

• (-3, 4); x = -4

Match the following.

• when a > 0

• parabola opens up

• y - intercept

• (0 , c)

• vertex

• axis of symmetry

• when a < 0

• parabola opens down

• (-1, 2); x = -1

• (2, 1); x = 2

• (1, -2); x = 1

• (3, -6); x = 3
