Learning how to find the inverse of a quadratic and using restrictions

The video tutorial covers the concept of functions, focusing on the function F(x) = x^2. It explains how to determine if a graph represents a function using the vertical line test. The tutorial then explores inverse functions, highlighting the horizontal line test to check if an inverse is a function. It demonstrates how to find the inverse of a function by swapping variables and solving for y. The video concludes by explaining how to restrict the inverse to the positive square root to make it a function.
