You can put this solution on YOUR website!
Domain: Ask yourself if there is any value that "x"
cannot take. The answer is none. So the Domain is all Real numbers.
Range: Ask the same question of "y". The answer is none.
So the Range is all Real numbers.
Function: Is there one "y" value for each "x" value?
The answer is yes. Therefore it is a function.
