Graphing Quadratic Functions in Vertex and Standard Form

What is the vertex of this parabola?

• (−1, 3)

• (−3, 11)

• (−2, 5)

• (0, 5)

What is the vertex of the parabola: y = 2(x - 3)² + 4

• (3,4)

• (-3,4)

• (3, -4)

• (-3,-4)

Identify the vertex and whether the graph opens up or down.

• (5, 2); opens up

• (5, 2); opens down

• (-5, 2); opens up

• (-5, 2); opens down

y = ax² + bx + c is

• a quadratic equation in vertex form

• a linear equation in vertex form.

• a quadratic equation in standard form.

• a linear equation in standard form.
