The cable for a suspension bridge is modeled by the equation
h(x) = (1/800)(x − 200)^2 + 30
--------------------------------------------------------------
where h metres is the distance above the base of the bridge
and x metres is the distance from the left side of the bridge.
---------
Determine the turning point of the graph of the equation.
Vertex:: (200,30/800) = (200,0.0375)
Determine the suitable values of x. [0,400]
-----
Note: h(0) = 80 ft.
-----
Determine the range of values of h.[0.0375,80]
What distance does the cable span?:: 400 ft
What is the closest distance of the cable from the base of the bridge?:: 0.0375'
What is the greatest distance of the cable from the base of the bridge?:: 80'
