Write the equation of a polynomial function with the given characteristics. Use a leading coefcient of 1 or -1 and make the degree of the function as small as possible. Crosses the xaxis at - 2, 0, and 4; lies below the xaxis between 2 and 0; lies above the xaxis between 0 and 4. E> O A. f(x)= -x3+2x2+3x O B. f(x)= -x3-2x2+3x O c. f(x)=x3-2x2-8x O D. f(x)=x3 +2x2 -8x
