Graphs of exponential functions Video transcript In this video, I want to introduce you to the idea of an exponential function and really just show you how fast these things can grow. Our independent variable x is the actual exponent.

However, if we put a logarithm there we also must put a logarithm in front of the right side. This is commonly referred to as taking the logarithm of both sides.

This is easier than it looks. It works in exactly the same manner here.

Both ln7 and ln9 are just numbers. Admittedly, it would take a calculator to determine just what those numbers are, but they are numbers and so we can do the same thing here.

Also, be careful here to not make the following mistake. We can use either logarithm, although there are times when it is more convenient to use one over the other. There are two reasons for this.

So, the first step is to move on of the terms to the other side of the equal sign, then we will take the logarithm of both sides using the natural logarithm. Again, the ln2 and ln3 are just numbers and so the process is exactly the same.

The answer will be messier than this equation, but the process is identical.

Here is the work for this one. That is because we want to use the following property with this one. Here is the work for this equation. In order to take the logarithm of both sides we need to have the exponential on one side by itself.Except as otherwise noted, the content of this page is licensed under the Creative Commons Attribution License, and code samples are licensed under the Apache Write exponential functions of the basic form f(x)=a⋅rˣ, either when given a table with two input-output pairs, or when given the graph of the function.

In mathematics, tetration (or hyper-4) is the next hyperoperation after exponentiation, but before plombier-nemours.com is defined as iterated exponentiation. The word was coined by Reuben Louis Goodstein from tetra-(four) and plombier-nemours.comion is used for the notation of very large plombier-nemours.com notation means ⋅ ⋅, which is the application of exponentiation − times.

1. Definitions: Exponential and Logarithmic Functions. by M. Bourne. Exponential Functions. Exponential functions have the form: `f(x) = b^x` where b is the base and x is the exponent (or power).. If b is greater than `1`, the function continuously increases in value as x increases.

A special property of exponential functions is that the slope of the function also continuously increases as x. In this video, I want to introduce you to the idea of an exponential function and really just show you how fast these things can grow.

So let's just write an example exponential function . Plot the graphs of functions and their inverses by interchanging the roles of x and y. Find the relationship between the graph of a function and its inverse.
