a rectangular hyperbola
a perpendicular
a parabola
a straight line
Answer is Right!
Answer is Wrong!
The correct answer
is D. A straight line.A straight line demand curve shows elasticity equal to unity at all points. This means that the percentage change in quantity demanded is equal to the percentage change in price.
A rectangular hyperbola demand curve shows elasticity greater than unity at all points. This means that the percentage change in quantity demanded is greater than the percentage change in price.
A perpendicular demand curve shows elasticity equal to zero at all points. This means that the percentage change in quantity demanded is zero, regardless of the
percentage change in price.A parabola demand curve shows elasticity less than unity at all points. This means that the percentage change in quantity demanded is less than the percentage change in price.
