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%.
