Math Problem Statement
Solution
To analyze the exponential function provided:
Step 1: Identify Growth or Decay
In an exponential function of the form , if (the base of the exponent) is:
- Greater than 1, the function represents exponential growth.
- Between 0 and 1, the function represents exponential decay.
Here, , which is less than 1, indicating that this is an exponential decay function.
Step 2: Determine the Percentage Rate of Decrease
The percentage rate of change can be calculated as follows:
- Subtract from 1: .
- Convert this to a percentage: .
Conclusion
This function represents an exponential decay with a percentage rate of decrease of 4%.

Here are some additional related questions for further exploration:
- How would the equation change if it represented a 6% decay?
- What is the significance of the initial value, 4600, in the context of this equation?
- How does the decay rate affect the speed at which the function approaches zero?
- What would the equation look like for a 4% growth instead of decay?
- How can you graph this function to visually observe the decay?
Tip: When identifying growth or decay, always check the base of the exponent. Values below 1 indicate decay, while values above 1 indicate growth.
