Quadratic Functions Vertex from Standard Form

Does this graph in the back have maximum or minimum value?

• maximum

• minimum

• neither

• both

The minimum of a quadratic function is

• The lowest point (vertex) on a graph when a parabola opens up; the point where the graph changes from decreasing to increasing

• The highest point (vertex) on a graph when a parabola opens down; the point where the graph changes from increasing to decreasing

The maximum of a quadratic function is

• The highest point (vertex) on a graph when a parabola opens down; the point where the graph changes from increasing to decreasing

• The lowest point (vertex) on a graph when a parabola opens up; the point where the graph changes from decreasing to increasing

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

• y = -2

• x = 3

• x = -3

• y = 2

Which best describes the vertex of a parabola?

• Any point on the parabola.

• A point on the x-axis.

What is the name of this form:
y = a(x - h)² + k

• vertex form

• standard form

• factored form

• zero form

Does the following quadratic equation have a maximum or minimum value? How can you tell?
y=x²+2x-3

• Minimum value, because the a value is positive

• Maximum value, because the b value is positive

• Maximum value, because the a value is positive

• Minimum value, because the c value is negative
