John and Chaney are fighting over who has the biggest banana. John's can be described by the region bounded by the functions y= -36/169(x-15/4)^2+ 9/4 and y = -3/10(x-15/4)^2 +4 on the interval (0, 7.5)
Chaney's can be described by the regions bounded by the functions y= -1/5(x-4)^2+1 and y=-2/5(x-4)^2+3 on the interval (1.7, 6.7).
