Quadratic Vertex Formula

What is the vertex of the quadratic function:
y = x² - 6x + 11?

• (3,2)

• (-3,-2)

• (-3,2)

• (3,-2)

Use the Formula h = \frac{-b}{2a} to get the x-value of the vertex in the equation: y=2x^2-4x+10

• 2

• -2

• 1

• -1

The formula x = -b/2a is used to find

• the roots

• the x-value of the vertex

• the y-intercept

• the axis of symmetry
