Identify domain and range of the given relation. Is it a function?

The correct answer is: Range = {-5,-2,0,3,2}

We have given some points of a function

(-1,-5) , (-5,-2) , (4,0) , (0,3), (2,2)
The first components of all given points are

-1, -5, 4, 0, 2

Domain = {-1, -5, 4, 0, 2}
The Second components of all given points are

-5,-2,0,3,2

Range = {-5,-2,0,3,2}
