Watch the video and then solve the problem given below. Click here to watch the video. \( f(x)=x^{3}+4 x^{2}-8 x-13 ; a=-8, b=-2 \) Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A. The function has at least one real zero between a and \( b \) because \( f(a)=\square \) and \( f(b)=\square \). (Simplify your answers.) B. The function does not have at least one real zero between a and \( b \) because \( f(a)=\square \) and \( f(b)=\square \). (Simplify your answers.) C. It is impossible to use the intermediate value theorem in this case.
