Understanding domain and range can be tough for students in Grade 12 Algebra I.

Many find it hard to see how these ideas relate to real-life situations. This can lead to confusion and frustration.

Some common challenges are:

• Misunderstanding the rules of a function can lead to wrong answers.
• Not realizing that some inputs don’t give valid outputs can make real-life applications harder.
• Ignoring the context of a problem can result in solutions that don’t make sense.

But there are ways to make it easier:

• Practicing how to find domains and ranges in different functions can really help students understand.
• Using graphs can show how domains and ranges work together, making it easier to see.
• Checking out real-world examples can make math concepts feel more relatable and easier to grasp.

In the end, while it can be tricky to understand domain and range, regular practice and real-life examples can help students get the hang of it!
