When the demand curve is negatively sloping, shape of total revenue curve is a straight line sloping upward from left to right. True or false?

True False Partially true Partially false

False

Shape of total revenue curve depends on demand curve. Like in perfect competition, when the demand curve is horizontal straight line parallel to x axis, total revenue curve is upward sloping straight line from left to right. But in imperfect markets like monopoly, when demand curve is downward sloping, total revenue curve is an inverted vertical parabola.
