Answer: Second option.

Explanation:

By definition, a relation is a function if for each input value (value of x) there is an unique output value (value of y).

1) For
f(0)=3 the input value is
x=0 and the output value is
y=3, obtaining the point (0,3) which is not true for the function f(x) shown in the graph.

2) For
f(5)=-1 the input value is
x=5 and the output value is
y=-1, obtaining the point (5,-1) which is true for the function f(x) shown in the graph.

3) For
f(3)=2 the input value is
x=3 and the output value is
y=2, obtaining the point (3,2) which is not true for the function f(x) shown in the graph.

4) For
f(2)=-2 the input value is
x=2 and the output value is
y=-2, obtaining the point (2,-2) which is not true for the function f(x) shown in the graph.
