Hello I'm new here ;) . I'm having a little trouble with this question: Is a function always a relation? Is relation always a function? :confused: Please explain your reasoning.:D

From what I remember a function is always a relation but a relation is not always a function.

Go to the Math source:

function

Functions versus Relations

Function (mathematics - Wikipedia, the free encyclopedia)

A Vertical line Test can easily Tell you if it is a function or not. :)

Great method assuming that the relation can be graphed easily.
