Suppose that Q: = {(x, y) R : x > 0 and y > 0} and that

Suppose that Q: = {(x, y) ˆˆ R : x > 0 and y > 0} and that f is a continuous function on R2 whose first-order partial derivative satisfies |fx|

for (x, y) ˆˆ Q, prove that F is bounded on Q.
[You may use polar coordinates to change variables in F.]
