Standard Form of a Quadratic

In the picture, what does the coordinate (0, -2), where the parabola crosses over the y-axis, represent?

• the x-intercept
• the minimum
• the axis of symmetry
• the y-intercept

On a graph, the value of x at the point where the line crosses the x-axis. Represented on B by the points (-2, 0) and (2,0) and on A by the origin.

• x-intercepts
• y-intercepts
• vertex
• axis of symmetry

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
