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) = -7x3 - 9x2 + 4x + 1
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 the same sign, therefore the function f has a real zero between -1 and 0.
C. f(-1) and f(0) have opposite signs, therefore the function f does not have 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.
