I need help with these two problems please, and please answer all parts and make it legible.

Use the two-path test to prove that the following limit does not exist. lim V4 '2x2 (x,y)40,0) y4 + x2 ( ..... 4 _ 2X2 What value does f(x,y) = y42 approach as (x,y) approaches (0,0) along the x-axis? Select the correct choice below and, if necessary, ll in the answer box to complete your choice. y + X 0 A- f(x,y) approaches D. (Simplify your answer.) 0 B. f(x,y) approaches 00. O C. f(x,y) approaches -00. O D. f(x,y) has no limit as (x,y) approaches (0,0) along the xaxis.
