# Is (-3,-2), (-1,0), (0,1), (1,2) a function?

Yes, the set of points (-3,-2), (-1,0), (0,1), (1,2) represents a function because each input value (x-coordinate) is associated with exactly one output value (y-coordinate).

Yes it is a function, i was wrong !

Jim says the correct explanation.

Two examples of functions using your points.

The particularity of your four points is their collinearity (=they are aligned).

Indeed, we can draw a *straight* line who is passing by all your points :

But this function is not unique, take a look of this :

Then {(-3,-2), (-1,0), (0,1), (1,2)} is a function, but you can't know more about other points. (Ex : x=2)

Yes, it is a function.

A function is a relation (a set of ordered pairs) with the additional property that: no two pairs have the same first element and different second elements.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
