Answer

The function with is an exponential decay function.

Solution

To determine the nature of the exponential function where , we can analyze the behavior of the function based on the value of .
  1. Exponential Growth: This occurs when the base is greater than 1. In this case, as increases, also increases rapidly.
  2. Exponential Decay: This occurs when the base is between 0 and 1 (i.e., ). In this case, as increases, decreases towards 0.
Since you are considering the case where , the correct answer is:
A. An exponential decay function.

The Deep Dive

When you set the base in the exponential function to be between 0 and 1 (i.e., ), you’re diving into the world of exponential decay. This means that as increases, the value of the function rapidly decreases toward zero. It’s like watching the sun set quickly over the horizon!
In real-world terms, exponential decay is commonly observed in processes such as radioactive decay, where unstable atoms lose energy over time, diminishing in quantity. It is also evident in scenarios such as depreciation of cars or the cooling of hot objects - both illustrating how quantities can decrease exponentially depending on initial values and conditions.
