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 = 0f(x) = 3x3 - 9x2 - 2x + 8
A. f(-1) and f(0) have the same sign, therefore the intermediate value theorem cannot be used to determine whether the function f has a real zero between -1 and 0. B. f(-1) and f(0) have opposite signs, therefore the function f does not have a real zero between -1 and 0. C. f(-1) and f(0) have the same sign, therefore the function f has a real zero between -1 and 0. D. f(-1) and f(0) have opposite signs, therefore the function f has a real zero between -1 and 0.
