A company uses the given quadratic function to model its profits, in thousands of dollars, where x is the number of years since 2006.
f(x) = 18x² + 202.61x + 1282.46 Based on the model, what is f(14) in thousands of dollars?
Substitute 14 in for x, and evaluate the function.
f(14) = 18(14)² + 202.61(14) + 1,282.46 {substituted 14 for x} = 18(196) + 2836.54 + 1,282.46 {evaluated exponent and multiplied 202.61 by 14} = 3,528 + 2836.54 + 1282.46 {multiplied 18 by 196} = 591 {added and subtracted from left to right} The profit is 591 thousand dollars Ask Algebra House
