Afunction is never, always, sometimes a relation

Always

A function is always a relation

Side note:
Not all relations are functions though. Consider this example
{(1,2),(3,4),(1,8)}
which is a relation but it's not a function. The reason why is because x = 1 leads to y = 2 and y = 8 at the same time.

That is what i got (fgx) hope this
