SUMMARY
The discussion confirms that if fx(x0, y0) exists, then the function g(x) = f(x, y0) is continuous at x = x0. This is established by recognizing that g(x) is effectively a function of a single variable, x, with y0 held constant. The continuity of g(x) can be analyzed using the principles of single-variable calculus, specifically focusing on the behavior of derivatives and limits.
