Question

Hi when finding the one sided limits on a graph what happens when there is no point on the graph at the function niether open or closed? does that mean it does not exist? or do you just make your own point and record it?

Answer 1

I think that point is not in the domain of the function i.e function is not defined at that point

Answer 2

thats what i thought, but just learned and some were that way on homework, so thanks for clarification.

Answer 3

So that means also that the limit does not exist?

Answer 4

No I think limit will exist but there will be no absolute value for function at that point

Answer 5

ok

Answer 6

say f(x) = 2 -infinity<x<10
-2 10>x > infinity
So here limit for f(x) x->10 is defined but f(10) is not

Answer 7

ok I think I understand. thank you.

Answer 8

np :)
