1. The problem statement, all variables and given/known data Find the volume of the region under the graph of f(x,y) = x+y and above the region y2≤x, 0≤x≤9 3. The attempt at a solution From these equations, x will be integrated from 0-9, but i'm not sure about y. My thinking is that y will be intgrated from 0-3 because y2≤x and the smallest value of x is 0, and the square root of 0 is 0, so that is the smallest y, and the largest x value possible is 9 and the positive quare root of 9 is 3, so this is the largest value of y, So I would integrate: ∫0-9∫0-3 (x+y)dydx. Is this correct or am I missing something, where the limits of integration also involve using f(x,y)?
