Making your own function machine is a fun way to learn about algebra! Here’s how you can do it:

1. Pick a Number: Start with a number called $x$.

2. Choose a Rule: Decide on a math operation. For example, you might want to add 3. This would be written as $x + 3$.

3. Find the Result: The result is what you get after using your rule. So here, the result would be $x + 3$.

4. Test Your Rule: Pick a few numbers for $x$. If $x = 2$, then the result would be $2 + 3 = 5$!

5. Try More Rules: Have fun experimenting with different operations, like multiplying by 2 or subtracting 1.

That’s all there is to it! Have fun creating your function machine!
