C(x) is just a parabola. Its minimum value is at the vertex, where
x = -b/2a = 7
Aki's Bicycle Designs has determined that when x hundred bicycles are built, the average cost per bicycle is given by C(x)
=0.1x^2−1.4x+8.096, where C(x) is in hundreds of dollars. How many bicycles should the shop build to minimize the average cost per bicycle?
