Functions and Exponential Analysis

This video tutorial explains how to use a graphics display calculator to solve equations using the numerical solve function, also known as n-solve. It highlights the importance of this skill across various topics in the AI course, particularly in topics 2 and 5. The video provides two examples: solving an exponential function related to hamster population growth and a logarithmic function related to sound intensity. It also discusses the limitations of numerical solve, such as only providing the leftmost solution in cases of multiple solutions, and suggests using plotting and analysis tools for more complex functions.
