## Video Transcript: Algebra Applications: Logarithmic Functions, Segment 1: What Are Logarithms?

### This is the transcript for the video of same title. Video contents: The mathematical definition of a logarithm is the inverse of an exponential function, but why do we need to use logarithms? This segment explains the nature of some data sets, where incremental changes in the domain result in explosive changes in the range. As a result, logarithms allow for the a way to present and analyze what would otherwise be unwieldy data.
