Finding Inverses and Simplifying Expressions

This video tutorial covers three main topics: finding a function's inverse, verifying if two functions are inverses of each other, and solving literal equations. The instructor provides step-by-step guidance on each topic, including swapping variables to find inverses, using composition to verify inverses, and factoring to solve literal equations. The tutorial emphasizes the importance of understanding algebraic manipulation and function notation.

What are the three main topics covered in this session?

• Understanding limits, continuity, and differentiability

• Solving quadratic equations, graphing functions, and finding derivatives

• Exploring matrices, vectors, and determinants

• Finding a function's inverse, verifying inverses, and solving literal equations

What is the first step in finding the inverse of a function?

• Graph the function

• Integrate the function

• Swap the variables x and y

• Differentiate the function

After swapping variables, what is the next step in finding a function's inverse?
