The graph of a quadratic function is called

• line

• parabola

• half oval

• vertex form

The axis of symmetry is _____________________ .

The minimum of a quadratic function is

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

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

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

Identify the vertex and whether the graph opens upwards or downwards.

• (-1, 4); opens downwards

• (1, 4); opens upwards

• (1, 4); opens downwards
