The roller coaster below is the shape of a parabola. The quadratic equation that represents the roller coaster is h(x) = - x² + 6x – 4, where h(x) is the height of the roller coaster in meters when x, in meters, is the distance from one of the bases under the roller coaster. What is the height of the roller coaster 3 meters from one of the bases under the roller coaster? Show your work.
