You can put this solution on YOUR website!
y+=+-abs%28x+%2B+6%29
By domain one means - for what values of x does y exist?
I can put any number I want in place of x, and I still get a perfectly
good value for y.
The domain of x is -infinity to + infinity.
The values I get for y are never positive however.
abs%28x+%2B+6%29 is always positive or zero (zero if x = 6).
The minus bofore the abs means y is always negative or zero.
So, the range is 0 to -infinity
