In an exponential function, where does the variable sit?

1. An exponential function is written as a fixed base raised to a variable power. 2. So the variable sits in the exponent rather than in the base. 3. That is the reverse of a power such as x squared, where the variable is the base. _Source: OpenStax Intermediate Algebra (CC BY 4.0), section 10.2 Evaluate and Graph Exponential Functions_
