Given:

The exponential function is

To find:

The percentage rate of increase or decrease.

Solution:

The general form of an exponential function is

        ...(i)

Where, a is the initial value, r<0 is the rate of decrease, r>0 rate of increase, x is time period.

We have,

It can be written as

          ...(ii)

On comparing (i) and (ii), we get

r>0, so the it is the rate of increase. Multiply it by 100 to get the percentage rate of increase.

Therefore, the percentage rate of increase is 7.4%.
