Solve the problem.A company has sales (measured in millions of dollars) of 50, 60, and 75 during the first three consecutive years. Find a quadratic function that fits these data, and use the result to predict the sales during the fourth year. Assume that the quadratic function is of the form y = ax2 + bx + c
A. y = 5x2 + 5x + 40; sales during the fourth year = $180 million
B. y = 
x2 - 
x + 
; sales during the fourth year = $151.25 million
C. y = -5x2 + 40x + 15; sales during the fourth year = $95 million
D. y = 
x2 + 
x + 45; sales during the fourth year = $95 million
