Consider the following(adsbygoogle = window.adsbygoogle || []).push({});

lim f(f(x))

x->-2

When looking at the graph of a function, if the function approaches -2 from above on the right

side, and approaches -2 from below on the left side, does the limit exist? I've been told it doesn't, but I don't understand why.
