Answer

{(–3, 2), (–2, 3), (–1, 2), (0, 4), (1, 1)}

Explanation

The options have the form:

$\lbrace(input_1,output_1),(input_2,output_2),...\rbrace$

In a function, every input can be related to only one output.

In the case of the first option, the input -1 is related to two outputs, 3 and 2, then it is not a function.

In the case of the second and third options, the input 0 is related to two outputs, 4 and 1, then they are not a function.
