Quadratics in Vertex Form Intercepts

A parabola has a vertex at (-3,2).
Where is the axis of symmetry?

• y = -2

• x = 3

• x = -3

• y = 2

Write y = x² - 18x + 52 in vertex form.

• y = (x - 9)² + 113

• y = (x + 9)² - 29

• y = (x - 9)² + 52

• y = (x - 9)² - 29

Convert the equation y= 5x² - 40x + 67 into vertex form.

• y= -5(x + 4)² + 13

• y= 5(x + 4)² - 13

• y=5(x - 4)² - 13

• y= 5(x - 13)² + 4

Which of the following is the correct equation for the given graph?

• f(x) = (x - 2)² - 1

• f(x) = (x + 2)² - 1

• f(x) = -(x + 2)² - 1

• f(x) = -(x - 2)² - 1
