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, b = 3f(x) = x3 + 5x2 + 12x + 8
A. f(2) and f(3) have the same sign, therefore f does not have a real zero between 2 and 3. B. f(2) and f(3) have the same sign, therefore the intermediate value theorem cannot be used to determine whether f has a real zero between 2 and 3. C. f(2) and f(3) have opposite signs, therefore f has a real zero between 2 and 3. D. f(2) and f(3) have opposite signs, therefore f does not have a real zero between 2 and 3.
