What is an exponential function?

a function whose value is a constant raised to the power of the argument, especially the function where the constant is e.

Step-by-step explanation:

According to the "dictionary," "exponential function" is a function whose value is a constant raised to the power of the argument, especially the function where the constant is e.

The exponential function is a mathematical function denoted by f(x)=\exp or e^{x}. It can be defined in several equivalent ways. Its ubiquitous occurrence in pure and applied mathematics has led mathematician W. Rudin to opine that the exponential function is "the most important function in mathematics".
