To find out the results of a function using a function table, you first need to know the function rule.
A function often looks like this:
f(x) = 2x + 3
In this rule, you replace x with different input numbers to get the output.
Here’s how to do it step by step:
Set Up Your Table:
Start by making a table with two columns.
Choose Your Inputs:
Pick some x values.
A good set could be numbers like -2, -1, 0, 1, and 2.
But feel free to choose any numbers you want!
Calculate Outputs:
For each x value, use the function rule to find the output.
For example, if x = 1, then you would find:
f(1) = 2(1) + 3 = 5.
Write that result in the output column.
Repeat:
Keep going! Plug in more x values until your table is complete.
Interpret:
When your table is full, you can easily see how the outputs connect to the inputs.
This helps you understand how the function works.
Overall, using a function table is a simple way to evaluate functions!
