On the coordinate plane, sketch a graph of the parabola that models the cables between the two towers. use a vertex point as (0,0) for your graph. (please just tell me how to find the roots of the parabola with the information:) )

Determine the coordinates of tips of the two towers.

Explain how you know that the absolute value of a in the parabola equation is less than one.
