suppose the function is for instance

y=3

here is a table  of y and x values:

    X           Y
-1              3
0                3
1                3
2                3
57              3
999            3
1000001    3


Try sketching those points on a graph and see what the line looks like.....

the line would be similar for any 'constant' value of Y
