Identifying Vertices of a Quadratic Function

Which equation has a vertex of (-3, 4)?

• y = (x + 3)² + 4

• y = (x + 3)² - 4

• y = (x - 3)² + 4

• y = (x - 3)² - 4

What is the vertex of the following equation? y = (x - 3)² + 5

• (3, 5)

• (-3, 5)

• (3, -5)

• (-3, -5)

If given the equation

y = (x + 5)² - 4,

what is the vertex of the parabola?

• (5, -4)

• (-5, -4)

• (5, 4)

• (-5, 4)

If the blue graph is f(x) = x² then the red must be...

• g(x) = x² - 5

• g(x) = x² + 5

• g(x) = (x - 5)²

• g(x) = (x + 5)²
