Show that the function f(x) = x* + 8x + 4 has exactly one zero in the interval [ - 1, 0]. Which theorem can be used to determine whether a function f(x) has any zeros in a given interval? A. Mean value theorem O B. Extreme value theorem C. Intermediate value theorem O D. Rolle's Theorem To apply this theorem, evaluate the function f(x) = x" + 8x + 4 at each endpoint of the interval [ - 1, 0]. f( - 1) = (Simplify your answer.)
