To determine if something is a function or relation, you would look at the x values and determine if every x value has 1 y value. any x vaue with more than one y value would be a relation.
this one would be a function because there only one y value for every x value
It is a decimal that does not terminate. 1/3 is equivalent to .3333333333 and so on. it never ends
