Using tables to understand how inputs and outputs in functions work is really helpful! Here’s how it goes:

1. Mapping Inputs to Outputs: Think of a function like a machine. You put in something, called an "input" (like a number), and get an "output" (another number) back. A table helps you see which input goes with which output, making it clear.

2. Seeing Patterns: When you organize inputs and outputs in a table, it’s easy to notice patterns. For example, if you have a function like $f(x) = 2x$, and you use inputs like $1, 2, 3$, you can see how the outputs double:

   • Input: $1$, Output: $2$
   • Input: $2$, Output: $4$
   • Input: $3$, Output: $6$

3. Checking for Functions: A table can help you check if something is really a function. Each input should have only one output. If the same input has different outputs, then it’s not a function!

Overall, tables are super useful for understanding how different numbers connect with each other!
