Step 1 :The Intermediate Value Theorem states that if a function is continuous on a closed interval [a, b] and k is any number between f(a) and f(b), then there is at least one number c in the interval (a, b) such that f(c) = k. In this case, we need to find the values of f(-4) and f(-2) and see if they have different signs. If they do, then by the Intermediate Value Theorem, there must be a zero between -4 and -2.
Step 2 :Calculate the value of the function at -4 and -2: \(f(-4) = -36\) and \(f(-2) = 4\).
Step 3 :Since \(f(-4) < 0\) and \(f(-2) > 0\), there must be a zero between -4 and -2 by the Intermediate Value Theorem.
Step 4 :Final Answer: \(\boxed{\text{C. Because } f(x) \text{ is a polynomial with } f(-4)=-36<0 \text{ and } f(-2)=4>0, \text{ the function has a real zero between -4 and -2.}}\)
