Using the power rule for integration, we have:
∫(11x^2 + 2x - 9) dx = (11/3)x^3 + x^2 - 9x + C
Evaluating this expression from x=0 to x=3 gives:
(11/3)(3)^3 + (3)^2 - 9(3) - [(11/3)(0)^3 + (0)^2 - 9(0)]
= 99 + 9 - 27 - 0
= 81
Using a graphing utility to evaluate the definite integral also confirms that the answer is C.
