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 = 1 and b = 2f(x) = 8x3 - 9x - 3

Question

A. f(1) and f(2) have opposite signs, therefore f does not have a real zero between 1 and 2.
B. f(1) and f(2) have the same sign, therefore the intermediate value theorem cannot be used to determine whether f has a real zero between 1 and 2.
C. f(1) and f(2) have the same sign, therefore f does not have a real zero between 1 and 2.
D. f(1) and f(2) have opposite signs, therefore f has a real zero between 1 and 2.
