Quadratic and Exponential STAAR Review

Axis of Symmetry

• The line that cuts the parabola in half

• The Highest or lowest point of the parabola

• The points where the parabola crosses or touches the x-axis

• The invisible line the exponential function never touches

Vertex

• The line that cuts the parabola in half

• The Highest (max) or lowest (min) point of the parabola

• The points where the parabola crosses or touches the x-axis

• The invisible line the exponential function never touches
