SUMMARY
The function F(x,y) = arctan(x + √y is continuous at points where the expression inside the arctan is defined. Specifically, the square root function √y requires y to be non-negative (y ≥ 0). Thus, the set of points at which F is continuous is defined by the condition that y must be greater than or equal to zero, allowing for all real values of x. The discussion highlights the importance of understanding the domain of the function and the implications of continuity in multivariable calculus.
