1. The problem statement, all variables and given/known data Let f(x, y) =((x^2)*y)/(x^4 + y^2) if (x, y) != (0, 0) , f(x,y) = 0 if (x, y) = (0, 0) . a) Is f continuous at (0, 0)? Prove your statement. b) Show that -1/2 ≤ f(x, y) ≤1/2 for all (x, y). I have used the two path test to show that it has not limit at 0,0 hence it is not continuous there. however, ı have no idea what I should do for the b part?Is there a algebratic way to show it or should we take differential etc.?
