17. Figure given below shows a suspension bridge. In a suspension bridge the deck is hur below
suspension cables on vertical suspenders. The cables are very strong and at the same time flexible
also This helps the suspension bridge to nullyfy strong winds. Note that a suspension bridge
represents a geometrical figure called a parabola. A parabola is represented by the equation​
