Nigel is riding on a roller coaster. One section of the track is in the shape of a parabolic curve, which can be modeled with the equation
f(x) = 0.13x2 - 5.8x + 75, where f(x) gives the roller coaster's height
above the ground in feet at a horizontal distance of x ft.
a. How high is the roller coaster at the beginning of this section?
b. What is the lowest height of the roller coaster?
