Sorry, I forgot to enter all the info before. Below is the updated info for the problem.

What's the best way to solve functions? I can do basic ones, but have trouble with the harder ones.

I'm having trouble with the following:

Inputs x 1, 2, 3, 4, 5

Outputs y 0, 2, 6, 12, 20

I have tried everything and can't come up with the equation. Please help! Also, if you have any tips on how to solve that would be great. Thanks!
