Vitamin C Decay and Functions

The video tutorial explains how to model the decay of Vitamin C in the body using exponential functions. It covers the continuous growth model, calculating decay rates in both minutes and hours, and determining the amount of Vitamin C left after a certain time. The tutorial also includes solving for the time it takes for Vitamin C levels to drop to a specific amount.
