This is multivariable calculaus question, please I need the answer to be hand-written. Please no guessing if you don't know don't answer

(Part A is two points; Part B is two points; Part C is two points.) Given mazb My): 3.4wa if (m,y)7(0,0) 0 2'1' (W!) = (0, 0) where a and b are nonnegative integers. For each part, determine whether x, 3}) satises the given condition for the specified values of a and I). Part A. For a 2 4 and b 2 1: f(as,y) is continuous at (0, 0). Part B. For a. 2 3 and b 2 1: f(:1:,y) goes to 1 as (95,31) approaches (0,0) along the y 2 m, and f(a:, y) goes to 1 as (25,31) approaches (0, 0) along the line y 2 :.I:. Part C. For a. 2 1 and b 2 1: f(:t,y) is not differentiable at (1,1)
