what is the shape of dd curve under (a) Perfectly elastic demand (b)

1.	what is the shape of dd curve under (a) Perfectly elastic demand (b) perfectly inelastic demand Â© Unitary elastic demand (d) Greater than unitary elasticdemand Less than unitary elastci demand ?
Answer» Solution :(a) Perfectly elastic DEMAND , Horizontal i.E dd curve is parallel to Y-axis. (b) Perfectly inelastic demand . Vertical i.e dd curve is parallel to Y-axis. (C) Unitary elastic demand. Rectangular hyperbola or LINEAR or linear dd curve forming `45^(@)` angle with both the axis. (d) Greater than unitary elastic dd. FLATTER demand curve. (e) Less than unitary elastic dd. steeper demand curve.
