The curve of best fit for the date y=-5x^2+60x+3715
For April which month 4 which means that x is 4
By substituting 4 for x in the equation we can determine y, the number of passengers that arrived on flights at the airport is determined thus.
y=-5*4^2+(60*4)+3715
y=-5*16+240+3715
y=-80+240+3715=3875
