• y = -x² + 2

• y = x² - 2

• y = -(x + 2)²

• A

• B

• C

If red represents y = x², which equation represents blue?

• y = 2x²

A quadratic is reflected down when the value of a is negative.

• TRUE

• FALSE

Consider a parabola that opens upward and has a vertex (-1, 3). Now find the equation of a new parabola that is reflected over the x-axis and translated 2 units down.

• y = -(x - 3)² + 3

• y = -(x - 1)² +2

• y = -(x + 1)² + 1

• y = -(x + 1)_² - 2
