The volume, V, in cubic metres, of a rectangular cargo container can be modelled by the equation: V(x) = 4x-21x +29x - 6 a) Determine possible dimensions (length, width and height) of the container expressed in terms of x in meters, that will result in this volume. b) What are the restrictions on the value(s) of xso that the volume of the rectangular container is not a negative value?
