lim x ➡0 (lim y ➡0 for ysinx/|x|) does not exist. Say true or false

The range of the function f(x, y) =√81-9x²-9y² is [0, 8] . Say true or false.

If f(x, y) ={ 1 if x=0 or y=0 and 0 , otherwise } then lim f(x, y) does not exist for limit (x, y) approaches to (0, 0).

The function f(x, y) ={x²y/x⁴ +y² , (x, y) ≠0 and 0 , (x, y) =0 }is not continuous at (0,0).

Say true or false.

If f(x, y) ={ 1 if x=0 or y=0 and 0 otherwise } then lim f(x, y) does not exist for limit (x, y) approaches to (0, 0).
