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) = 4x5 - 5x3 - 8x2 + 5
A. f(1 ) and f(2) have opposite signs, therefore the function f has a real zero between 1 and 2. B. f(1 ) and f(2) have the same sign, therefore the function f has a real zero between 1 and 2. C. f(1 ) and f(2) have opposite signs, therefore the function f does not have a real zero between 1 and 2. D. 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.
