Provide an appropriate response.Suppose the graph of a quadratic equation has two x-intercepts. How could you use the intercepts to find the vertex of the graph?
What will be an ideal response?
Find the average of the values of the x-coordinates of the x-intercepts to find the x-coordinate of the vertex. Then substitute this value for x in the quadratic equation to find the y-coordinate of the vertex.
