The volume V (in cubic feet) of a rectangular room can be modeled by V (r) = 2x³ – 14x² + 20x, where z is the length (in feet) of the room. Factor the function. Use you. factorization to determine the values of r for which the model makes sense. The function can be factored as V (z) = 2z' - 14r + 20z = The model makes sense for z>
