Key Features of Quadratics

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

Which of the following is the vertex of the graph?

• (2, 0)

• (-2, 0)

• (0, 4)

• (-1, 3)

What is the axis of symmetry for this graph? 

• x = 2

• x = -4

• y = -4

• there is not one
