Quadratics and Vertex

Given: y = 2(x - 5)² + 6, the vertex is

• (2,-5)

• (-5,6)

• (2,6)

• (5,6)

What is the vertex?
f(x) = -x² - 4x + 12.

• (-2, 16)

• (2, 0)

• (2, 4)

• (-2, 4)

How many zeros does this parabola have?

• 3

• 2

• 0

• 1

Match each quadratic equation to its vertex

• (-3, 5)

• y = (x + 5)² - 3

• (5, 3)

• g(x) = (x + 3)² + 5

• (3, 5)

• f(x) = (x - 3)² + 5

• (-5, -3)

• h(x) = (x - 3)² - 5

• (3, -5)

• j(x) = (x - 5)² + 3
