Quadratic Functions key characteristics.

What is the term used to describe the x-intercepts of a quadratic function?

• Vertex

• Range

• Zeros

• Domain

Which point on the graph of a quadratic function represents the maximum or minimum value?

• Slope

• X-intercept

• Y-intercept

• Vertex

What is the y-intercept of a quadratic function?

• The point where the graph crosses the y-axis

• The point where the graph crosses the x-axis

• The highest point on the graph

• The lowest point on the graph

How is the range of a quadratic function determined?

• By the slope

• By the y-intercept

• By the x-intercepts

• By the vertex

Match each quadratic equation to its vertex
