# How do you know if (4,5) (3, -2) (-2,5) (4,7) is a function?

To determine if the given set of points represents a function, we need to check if each input value (x-coordinate) corresponds to exactly one output value (y-coordinate).

We can see that the x-coordinate 4 corresponds to two different y-coordinates: 5 and 7. Therefore, this set of points does not represent a function because it fails the vertical line test.

As soon as there is a choice for y, it is NOT a function.

It's not a purpose.

A function can only have ONE y-value for every x-value.

It is NOT a function as soon as y has a choice.

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.
