## VIDEO: Algebra Applications: Logarithmic Functions |
In this episode of Algebra Applications, students explore various scenarios that can be explained through the use of logarithmic functions. Such disparate phenomena as hearing loss and tsunamis can be explained through logarithmic models. |
Applications of Exponential and Logarithmic Functions, Exponential and Logarithmic Functions and Equations, Graphs of Exponential and Logarithmic Functions | |

## VIDEO: Algebra Applications: Logarithmic Functions, Segment 1: What Are Logarithms? |
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. |

## VIDEO: Algebra Applications: Logarithmic Functions, Segment 2: Hearing Loss |
We live in a noisy world. In fact, prolonged exposure to noise can cause hearing loss. Students analyze the noise level at a rock concert and determine the ideal distance where the noise level is out of the harmful range. Using the TI-Nspire’s Geometry tools, student create a mathematical simulation of the decibel level as a function of distance. |

## VIDEO: Algebra Applications: Logarithmic Functions, Segment 3: Tsunamis |
In 1998 a devastating tsunami was triggered by a 7.0 magnitude earthquake off the coast of New Guinea. The amount of energy from this earthquake was equivalent to a thermonuclear explosion. Students analyze the energy outputs for different magnitude earthquakes. Using the Graphing tools, students explore the use of a logarithmic scale to better analyze exponential data. |
