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.

Define Vertex

• Where the parabola touches or intersects the x-axis

• The highest or lowest point on the graph

• Where parabola line touches or intersects the x- axis, also called the x-intercept

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