A bridge is supported by parabolic arches that go below the water level. The structure of the
bridge arches can be modeled by the function y = 2x² - 12x – 1, where x is the width of the arch, in
kilometers, and y is the depth of the arch, in meters, relative to the water level.
A) What is the width of the bridge at the arch's deepest point?
B) How far below the water level is the arch at its lowest point?
C) What is the width of the bridge when the arch has a depth of -15 meters?
