Transformations of the Logarithmic Function

In this video I outline how to apply transformations to the logarithmic function using the mapping rule. I review the typical transformations for a function which are vertical stretch/compression, horizontal stretch/compression, vertical translation, and horizontal translation. I go over what form the function should be in to ensure accurate transformations of various points. Using the mapping rule, we take points on the parent function graph and transform those points to get the transformed graph. We go over two example problems that involve transforming the logarithmic graph.

This series is tailored to cover all things related to logarithms. This involves, properties of logarithms, logarithm rules and laws, transformations of log functions, solving logarithmic equations and more!
