• V(-8, 7)

• V(-8, 3)

• V(8, 10)

• V(16, -2)

What is the vertex of y= x² - 8x + 14 ?

• (2, 4)

• (-4, -2)

• (4, -2)

• (-2, 4)

What is the vertex?

y = x² + 6x - 5

• -3

• -14

• (3, -14)

• (-3, -14)

Find the vertex of
f(x) = -x² - 4x + 12

• (-2, 16)

• (2, 0)

• (2, 4)

• (-2, 4)

Where is the axis of symmetry for this parabola?

• x = −1
