A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of
the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram: Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).
as the function is polynomial domain exist for all real number ie (-infinity to + infinity) but range exist (0 to +infinity ) due to modulus negetive range do not exist
