limit does not exist

x tends to zero means we have to take 0+.Because in the left
neighbourhood of 0 function is undefined.For functions only we
find limits.
Therefore the limit is 0.

lhl is not equal to rhl as it does not exist
hence limit does not exist

No need to find LHL .Because in the left nbd of 0 function not defined.How can u find limit for relations?
Limit of logx when x tends to 0 means u have to take0+.The answer
is -infinity.
Limit of square root of 2-x means u have to take 2-.The answer is 0.
U should not consider 2+.Bcause after 2 function is not defined.
There are so many examples are there.Hope u got it.

The limit really means 0+ in this case so the LHL will not come into play as someone pointed out. Therefore the answer will be 0.

Venkat, I'm confused as to why you say the function is not defined after 2? Maybe I've read things wrongly
