Ageneral exponential demand function has the form q = ae−bp (a and b nonzero constants). (a) obtain a formula for the price elasticity e of demand at a unit price of p.

Step-by-step explanation:

The Elasticity(E) of demand at a unit price of p is given by:

As per the statement:

A general exponential demand function has the form :

where, A and b is non zero constants.

Using derivative formula:

First find the derivative of q with respect to p.

⇒

Using

⇒

then;

⇒

Therefore, a formula for the price elasticity E of demand at a unit price of p is,
