Since x = 2 maps to both y = 0 and y = 3, this means that the given relation is NOT a function.

Keep in mind that each x must map to only EXACTLY ONE y value for it to be a function.

Domain: {-2, 2, 3}

Range: {0, 1, 3}

Not a function because 2 has two correspondiing y-values.

Domain: {2,-2,3}
Range: {0,1,3}
