Answer:
<h2>A. An exponential parent function.</h2>
Step-by-step explanation:
The given function is exponential because it has the variable as the exponent.
In addition, parent functions refer to basic functions, that is, the simplest form of a function, which more complex versions are obtained by transformation. In this case, the given function is a simple form of an exponential function, that's why is called an exponential parent function.
