• Vertex

• Maximum

• Axis of Symmetry

• Maximum

Does the quadratic have a max/min vertex, and does the parabola open up/down?

• max/ opens down
• min/ opens up
• max/ opens up
• min/ opens down

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

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

• maximum
• minimum
• neither
• both
