Astudy of driving costs based on 2012 medium-sized sedans found that the average cost (car payments, gas, insurance, upkeep, and depreciation) in cents per mile is approximately:
c(x) = 1910.5/x^1.72 + 42.9 (5 β€ x β€ 20)
where x (in thousands) denotes the number of miles the car is driven each year.
show that the graph of c is concave upward on the interval (5, 20).
