You can put this solution on YOUR website!
y is always at 2 so no matter what x you have y will stay at 2
1,2
2,2
3,2
4,2
its a horizontal line at (0,2)
domain is what the x's are and range is what the y's are
y is always 2 so the range = {2}
x can be any numer negative or possitive so domain ={-infinity,infinity}
