What type of elasticity is shown at the top of the demand curve?
What type of elasticity is shown at the bottom of the demand curve?

Zoom in on the percent change in price from A to B, then B to C, then C to D.
Now do the same for the percent change in quantity from A to B, then B to C, and then C to D.
Write down what you notice.
Then, explain the difference between a curved and straight line in terms of elasticity.
