Graphing Exponential and Logarithmic Functions

This video tutorial covers graphing exponential and logarithmic functions, focusing on transformations such as vertical stretch, compression, and reflection. It uses caffeine decay as a practical example to illustrate exponential decay and how transformations affect graph shapes. The tutorial also explains how to apply these transformations to model real-world scenarios, like caffeine consumption, and provides strategies for accurately plotting graphs.

How can we modify the basic exponential decay model to show the amount of caffeine left in the body?

What happens to the graph of an exponential function when 'a' is less than 1?
