B. $3,900,000
C. $3,899,600
D. $3,900,600
corresponds to 1986.
This set of data can be modeled by f(x) = ax2 + bx + c, where x represents the year. Find a linear system for which the solution represents the values of a, b, and c. Use technology to solve this system. Then, using the quadratic equation, predict the revenue for the year
