Let f be a function of two variables whose domain D includes points arbitrarily close to (a, b). Then we say that the limit of f(x, y) as (x, y) approaches (a, b) is L and we write lim(x,y)->(a,b) f(@, y) = L. Which of the following statements are correct about the precise definition e - 6 of the limits? O The 'close' means that (x, y) such that 0 (x - a) + (y -b)
