How to Multiply Radical Expressions In this lesson, we are only going to deal with square roots only which is a specific type of radical expression with an index of [latex]\color{red}2[/latex]. If you see a radical symbol without an index explicitly written, it is understood to have an index of [latex]\color{red}2[/latex]. Below are the basic…
Finding the Inverse of an Exponential Function I will go over three examples in this tutorial showing how to determine algebraically the inverse of an exponential function. But before you take a look at the worked examples, I suggest that you review the suggested steps below first in order to have a good grasp of…
Finding the Inverse Function of a Square Root Function To find the inverse of a square root function, it is crucial to sketch or graph the given problem first to clearly identify what the domain and range are. I will utilize the domain and range of the original function to describe the domain and range…
Finding the Inverse Function of a Rational Function Finding the inverse of a rational function is relatively easy. Although it can be daunting at first, you will get comfortable as you study along. In this lesson, I have prepared five (5) examples to help you gain a basic understanding on how to approach it. You…
Finding the Inverse Function of a Quadratic Function What we want here is to find the inverse function – which implies that the inverse MUST be a function itself. Otherwise, we got an inverse that is not a function. Not all functions are naturally “lucky” to have inverse functions. This happens in the case of quadratics because they all…
