When you're faced with a word problem, the first step is to read carefully and identify the key elements - what's the question asking, and what information do you have? It's like being a detective, searching for clues to solve the mystery. Take your time, and don't be afraid to ask yourself questions like "what's the unknown?" or "what's the overall goal?"
Once you've got a handle on the problem, it's time to define the variables - what are the inputs and outputs? This is where things can get a little tricky, but stick with it - you're making progress! Consider using real-world examples to help illustrate the concept, like a bakery selling cookies - the domain might be the number of cookies sold, while the range is the total amount of money made.
Now that you've defined your variables, it's time to identify any restrictions - are there any limits on the inputs or outputs? This is like checking the road conditions on your trip - you need to know if there are any roadblocks or detours. For example, if you're modeling a situation where a company can't sell a negative number of products, you'd need to restrict the domain to only positive numbers.
