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, b = 3f(x) = x4 - 7x3 + 11x2 + 10x + 18
A. f(1) and f(3) have opposite signs, therefore f has a real zero between 1 and 3. B. f(1) and f(3) have opposite signs, therefore f does not have a real zero between 1 and 3. C. f(1) and f(3) have the same sign, therefore f does not have a real zero between 1 and 3. D. f(1) and f(3) have the same sign, therefore the intermediate value theorem cannot be used to determine whether f has a real zero between 1 and 3.
