How to Find the Domain and Range of Piecewise and Rational Functions | Cole's World of Mathematics

Welcome back to Cole's World of Mathematics! In this video, we’ll guide you through two essential examples on how to find the domain and range of functions that have been graphed. We’ll be focusing on a piecewise function and a rational function, helping you master these critical concepts step-by-step.

Understanding how to identify the domain and range from a graph is a key skill in mathematics, especially in algebra and calculus. We’ll break down each example, showing you how to interpret the graph, determine where the function exists, and how to pinpoint the range of values it covers.

By the end of this tutorial, you’ll have a clear understanding of how to approach these types of problems, making you more confident in your math abilities. This video is perfect for students, educators, or anyone looking to sharpen their graph interpretation skills.
