What's the function?
x= 2, y=14
x=10, y=54
x=8, y=44
x=?, y=34
x=?, y=104
x=?, y=31
I thought it was multiply by 5, add 4 but that won't work for the last one where y=31. Help!

I agree with you on your choice of the rule.
Functions can work with decimal numbers as well. So I would say x=5.4 solves the mystery of the last one.
