Parts of a Quadratic in Vertex Form

Write an equation in vertex form given the following transformations to the parent function: Translated seven units right and 2 units up

• y = (x - 7)² + 2

• y = (x + 7)² - 2

• y = (x + 2)² + 7

• y = (x - 2)² - 7

Write an equation in vertex form given the following transformations of the parent function: Stretched by a factor of 2 then four units left and one unit down.

• y = 2(x + 4)² + 1

• y = 2(x - 4)² - 1

• y = 2(x + 4)² - 1

• y = 2(x - 4)² + 1

The vertical line that divides your quadratic graph into two equal parts is called the (choose all that apply):

• line of symmetry

• axis of symmetry

• vertex

• foldline

Looking at the graph, what do you think are the x-intercepts?

• -3 and 1

• -1 and 3

• -2 and 0

• -1 and -4
