I do not understand this...
Determine the infinite limit:
lim x-->-3+ f(x); f(x) = x+2/x+3
I looked at the numerator and denominator...
(x+2) approaches -1 as x gets closer to -3 from the right and
(x+3) approchaes 0 as x gets closer to -3 from the right
How do I know that the function f(x) has an limit of negative infinity?
How do I know that the limit is infinite at all? (Why not just "does not exist")
