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 = -2 and b = -1f(x) = 6x4 + 2x3 - 2x - 7
A. f(-2 ) and f(-1) have opposite signs, therefore f does not have a real zero between -2 and -1.
B. f(-2 ) and f(-1) have opposite signs, therefore f has a real zero between -2 and -1.
C. f(-2 ) and f(-1) have the same sign, therefore the intermediate value theorem cannot be used to determine whether f has a real zero between -2 and -1.
D. f(-2 ) and f(-1) have the same sign, therefore f does not have a real zero between -2 and -1.
