Maxy, you need to rework your post. I expect it hasn't been answered because we don't know what you're asking.

Complete function table. Then I need to write a rule for the function. I typed it as it shows on the function colum box. Do I subtract to get the missing number ? Like -3 Input doesn't have anything next to it in the output column.

My brother didn't explain what he was asking enough.
