Aki’s Bicycle has determined that when x hundred bicycles are built, the average cost per bicycle is given by C(x)=-0.2x^2-0.1x+9.743, where C(x) is in hundreds of dollars. How many bicycles should the shop build to minimize the average cost per bicycle? They should build? bicycles

Answer 1

With minus signs in front of both of the first two terms, the average cost keeps decreasing with increasing x.
