Just reverse the x and y values in the ordered pairs. Then check if any of the ordered pairs have the same first number. If they do, it's not a function.

Yep. You would do the same. Is the inverse a function or not?

does this rule apply to all functions?

Yes. The 2 is paired with more than 1 y value

Absolutely. learn these lessons about functions well because you will be involved with functions for as long as you study math.
