the function h(x)=1/98x^2 describes h(x), the height of part of a roller coaster track, where x is the horizontal distance in feet from the center of this section of the track. The towers that support this part of the track are the same height and are 150 feet apart. which is the best estimate of the height of the towers?
obviously x goes from -75 to +75
So, 1/98 * 75^2 = 57.4 feet high
