lim x->0 from the right of ln(4/x^2)
I think it is infinity but I'm not sure how to prove that? I know that if you divide by zero that will give you infinity and I can see that from the graph. However that logarithm being there is making things a bit confusing. I feel like I might be missing a step because of that. Can I just pull out that 4 and take the limit of the rest of the function and then that will give zero?
No, The result is not infinity always.

undefined if .
What do you mean by "pull out that 4" ??!
In general : !!
Now take the limit, And clearly it infinity.
If you see the graph of , you will see that y-axis is a vertical asymptote.
which prove what do you want.
