$${f (x, y) = x^2 + x y + y^2}$$

continuous?

How do I go about solving such problems?

f(x,y) = \frac{x^2+xy+y^2}{x-y}$$you could invoke that polynomials are continuous, so the quotient of two polynomials is continuous except where the denominator is zero. So this example would be continuous except on the line ##y=x##.
