For this problem I understand how to do everything.
For the green (Square root of X is first because it is LEFT on the Graph. and they negative the (X/3) because it is on the RIGHT of the Graph.
But why is it for the answer highlighted in BLUE. Why is it (3y - (Y^2))?
Shouldn't it be ((Y^2) - 3Y)? Since (Y^2) is on TOP?
Aren't I suppose to use Top - Bottom on this?
