From the graph shown it can be seen that the bridge is represented by a parabola with vertex of (5, 8) and roots of 1 and 9.
Recall that the vertex form of the equation of a parabola with vertex (h, k) is given by
Thus, the equation of the given graph in vertex form is given by
Also, recall that the equation of a parabola with roots, p and q, is given by
Thus the equation of the given graph can be given by
To get the value of a, we equate both equations and solve as follows:
Therefore, the <span>function that Lindsay used to create her design is
