Front

When did the paper airplane land back on the ground if the graph shows its path?

Back

Front

At what price will the maximum profit be achieved if the graph shows price on the x-axis vs profit on the y-axis?

Back

$35.

Front

What is the vertex of the quadratic function?

Back

(-2,-1).

Front

Define a parabola.

Back

A parabola is a symmetric curve formed by the intersection of a cone with a plane parallel to its side.

Front

What are the roots of a quadratic equation?

Back

The roots are the values of x where the quadratic equation equals zero.

Front

What does the axis of symmetry represent in a parabola?

Back

It represents the vertical line that divides the parabola into two mirror-image halves.

Front

How do you find the vertex of a quadratic function in standard form?

Back

The vertex can be found using the formula (-b/2a, f(-b/2a)).

Front

What is the significance of the leading coefficient in a quadratic function?

Back

The leading coefficient determines the direction of the parabola's opening (upward or downward).
