Name the vertex to the given quadratic graph

• (2,3)

• (3,2)

• (0,-1)

• (4,-1)

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

What is the vertex of the graph?

• (2, 4)

• (3, -1)

• (0, 8)

• (4, 2)
