This video tutorial explores inverse functions, focusing on three sets of parent functions: quadratic and square root, cubic and cubed root, and exponential and logarithmic. It explains how to identify inverses through graph reflection and value tables, and demonstrates proving inverses using composition of functions. The video concludes with resources for further learning.

What is the main focus of the video?

• Studying logarithmic functions

• Learning about quadratic equations

• Understanding inverse functions and their properties

• Exploring different types of functions

Which function is the inverse of y = x^2?
