To finish it off, this is what we would do algebraically:
This limit has the form of
So let . Thus, as , as well.
So our limit transforms from to
Does this make sense?
yes thank you that helped a lot.
could u help me with this other one please?
I'm supposed to
a: use graphs and tables to find lim x approaching infinity f(x)
b: lim x approaching negative infinity f(x)
c: Identify all horizontal asymptotes
