say we want the limit of x -> -4 for f(x) = (2x^2 + 6x + 8) / (x^2 + 4)
is it not possible to simplify the numerator? I am guessing I did the wrong thing when I simplified the numerator to 2((x + 2)(x + 4))?
So I have some questions.
1. Is it possible to simplify the numerator?
2. If the numerator was actually 2((x + 2)(x + 4))... would the limit of x -> -4 be 0.5?
3. Is the answer to the original question infinity?
