Would someone please help me with this question, cheers:)

(a) Let f : R2 -> R be given by 7 pts x2 y if (x, y) # (0, 0), f (x, y ) * 4 + 2 2 if (x, y) = (0, 0). Identify the set of points in R at which f is continuous. Justify your answer. [This means that you must explain why the function is continuous where you say it is, and also prove that it is discontinuous at other points.] Write your solution here
