The Shape of the Main Cable on a Suspension Bridge

Short Answer

The shape of the main cable on a suspension bridge can be described by the function
where y is the height of the cable (in feet)above the roadbed and x is the horizontal distance (in feet)from the center of the bridge.A cross support passes by the cable,and its position can be described by the function
Where does the cross-support intersect the cable? Use a graphing calculator to answer the question by finding the point(s)of intersection of the two equations.
