Answer 1

Answer:

The value of 1(x-a) as lim x tends to "a"does not exist .why?

Because if you approach it from the right hand side (a+),you'll notice that you get closer to +infinity.

{ a+means, infinitesimally greater than a}

However when you apporach it from the left hand side ,(-a), you'll get closer to -infinity .

{ a means ,infinitesimally smaller than a}.

since approaching "a" from both sides , give us different values , hence therefore limit Does not exist for this case.

Thus is your answer

The answer is a
