An exponential function can either represent a growth or decay.
- The price of fuel A is increasing.
- Fuel B recorded a greater percentage change in price
<u>Part A</u>
For fuel A, the exponential function is given as:
An exponential function is represented as:
Where b represents the rate.
By comparison
Since b (i.e. 1.04) is greater than 1, then the price of fuel A is increasing.
<u>Part B</u>
The table represents an exponential function.
The rate of fuel B is calculated by dividing the current price by the immediate previous price.
So, we have:
By comparison, 1.06 is greater than 1.04 (the rate of fuel A).
Hence, fuel B recorded a greater percentage change in price
