What Do Domain and Range Mean in Functions?
Let’s explore the fun world of functions together!
Domain: The domain is all the possible input values (or "x-values") that a function can take. Think of it like the "approved ingredients" for a recipe! 🍽️ For a function written as , you can find the domain by checking which x-values won’t cause problems, like dividing by zero or finding square roots of negative numbers.
Range: The range is all the possible output values (or "y-values") that a function can give us! 🌈 It tells you what results come out when we use our approved inputs in the function.
Understanding these ideas will help you get really good at working with functions! Keep practicing and have fun learning! 🎉
