📚 Grade 9 Mathematics | Domain and Range of Functions
Every graph tells a story—you just need to know how to read it! 📈 Today, we'll learn how to identify the domain (all possible x-values) and the range (all possible y-values) by carefully observing graphs, endpoints, and arrows.
Remember: Read left to right for the domain, and bottom to top for the range. Keep practicing, ask questions, and don't be afraid to make mistakes—every mathematician starts by exploring. Let's graph our way to success! 💙📖 "
