Check all the statements that are true below for the quadratic function

.

When

is negative, the graph always opens down. When

is positive, the graph always opens down. When

is negative, the graph always opens down.

Check all the statements that are true below for the quadratic function

is negative, the graph always opens up.

The graph of any quadratic function is called a parabola. The vertex of a parabola is its turning point. Check all the statements that are true below for the quadratic function

.

When

is positive, the graph has a vertex above the xAxis. When

is negative, the graph has a vertex above the xAxis. When

is negative, the graph has a vertex above the xAxis.
