Match the following term with the best definition.

• vertex

• parabola

• The shape of a quadratic function

• axis of symmetry

• The highest or lowest point

• Axis of symmetry equation

• The line of reflection of a quadratic function

• Quadratic Function Equation

Define X-intercept

• The highest or lowest point on the graph.

• Where the parabola touches or intersects the x-axis.

• Where the parabola touches or intersects the y-axis.

• A line that divides the graph into two equal parts. i.e. cuts the graph in half.
