$(- 1, 0)$ , $(- 2, 1)$ , $(4, 3)$ , $(3, 4)$

Step 1

Since for each value of $x$ there is one and only one value of $y$ , the given relation $(- 1, 0), (- 2, 1), (4, 3), (3, 4)$ is a function.

The relation is a function.

Step 2

Since the relation is a function and for each value of $y$ there is one and only one value of $x$ , the given relation $(- 1, 0), (- 2, 1), (4, 3), (3, 4)$ is a one-to-one function.

The relation is a one-to-one function.
