Evaluate the function for the given values of a and b. Then use the intermediate value theorem to determine which of the statements below is true.a = -2 and b = -1f(x) = 9x3 - 8x + 3
A. f(-2) and f(-1) have the same sign, therefore f does not have a real zero between -2 and -1. B. f(-2) and f(-1) have the same sign, therefore the intermediate value theorem cannot be used to determine whether f has a real zero between -2 and -1. C. f(-2) and f(-1) have opposite signs, therefore f does not have a real zero between -2 and -1. D. f(-2) and f(-1) have opposite signs, therefore f has a real zero between -2 and -1.
