About Lesson
a) TVC: inverse S-shape: so follow the law of variable proportion. It means at the initial stage of production, productivity increases as more variable factors used and average variable cost falls.
b) TFC: Straight line parallel To the output axis

Average total cost (ATC) or Average cost – total cost per unit of output (AC=TC/ y= AFC+AVC).
