Exploring Quadratic Equations
is the vertex form of a quadratic equation. The vertex is the point on the quadratic. The vertex is the minimum or maximum of the quadratic.
is the standard form of a quadratic equation.
Move slider . See the width of the quadratic change. See the direction of the quadratic change when is a negative number. Positive give the quadratic a minimum point. Negative give the quadratic a maximum point.
Move slider . See the horizontal position of the quadratic change. Positive values keep the minimum or maximum of the quadratic to the right of the -axis. Negative values keep the minimum or maximum of the quadratic to the left of the -axis.
Move slider . See the vertical position of the quadratic change. Positive values keep the minimum or maximum of the quadratic above the -axis. Negative values keep the minimum or maximum of the quadratic above the -axis.
