Parent Graph Quadratics

What is the vertex of the following equation:
y=-3(x-2)² - 4?

• (-2,-4)

• (2,-4)

• (3,-4)

• (2,4)

Using the graph of y = -1.5x² + 12x - 23 shown here, what are the values of x when y = -5?

• x = 4

• x = 2, 6

• x = 3.2, 4.8

• cannot be determined on the graph

What is the quadratic parent function?

Which graph will have the farthest vertical shift away from the quadratic parent function?

• g(x) = -x² + 9

• g(x) = 5x² + 1

• g(x) = 0.2x² - 11

• g(x) = -3x² - 6

Which statements are true about the quadratic parent function? Select all that apply.
