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 = 0, b = 5f(x) = x3 + 3x2 + 6x + 4
A. f(0) and f(5) have opposite signs, therefore f does not have a real zero between 0 and 5. B. f(0) and f(5) have the same sign, therefore the intermediate value theorem cannot be used to determine whether f has a real zero between 0 and 5. C. f(0) and f(5) have opposite signs, therefore f has a real zero between 0 and 5. D. f(0) and f(5) have the same sign, therefore f does not have a real zero between 0 and 5.
