ANSWER
Exponential growth
Step-by-step explanation
We want to identify if the given function is an exponential growth or decay function:
![y=(2)^x](https://img.qammunity.org/2023/formulas/mathematics/college/98099vr9uhuwu3rj6xiabrv7qundz1a8js.png)
An exponential function is given generally as:
![y=a(b)^x](https://img.qammunity.org/2023/formulas/mathematics/college/x4kto8751eypenmr0i3prbmrtznyb1ero8.png)
where a = initial amount
b = exponential factor
For an exponential function, when b is greater than 0 or less than 1, the function is a decay function while when b is greater than 1, it is a growth function.
The given function has an exponential factor of 2. This is greater than 1.
Hence, the function is an exponential growth function.
