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 = 3 and b = 4f(x) = -2x4 + 5x3 + 6x + 10

Question

A. f(3 ) and f(4) have the same sign, therefore the intermediate value theorem cannot be used to determine whether f has a real zero between 3 and 4.
B. f(3 ) and f(4) have the same sign, therefore f does not have a real zero between 3 and 4.
C. f(3 ) and f(4) have opposite signs, therefore f does not have a real zero between 3 and 4.
D. f(3 ) and f(4) have opposite signs, therefore f has a real zero between 3 and 4.
