What are Exponential and Logarithmic Functions? Exponential Function Definition: An exponential function is a Mathematical function in the form y = f(x) = b x, where “x” is a variable and “b” is a constant which is called the base of the function such that b > 1. The most commonly used exponential function base is the transcendental ...

Let’s review some background material to help us study exponential and logarithmic functions. Exponential Functions. The function \(f(x) = 2^x\) is called an exponential function because the variable, \(x\), is the exponent. In general, exponential functions are of the form \(f(x)=a^x\), where \(a\) is a positive constant. There are three ...

Functions of the form f(x) = kbx, where kand bare constants, are also called exponential functions. Logarithmic Functions Since an exponential function f(x) = bxis an increasing function, it has an inverse, which is called a logarithmic function and denoted by log b. (Here we are assuming that b>1. Most of the conclusions also hold if b<1.)
