I'm doing some practice questions and I've encountered a wall. The question is:
Find the limit of the function $(\ln4x-\ln(x+7))$ as $x \rightarrow \infty$.
the indeterminate form is $\infty-\infty$, so I'm not sure how to advance from here. I think I would like $f(x)/g(x)$ form, but I'm not sure how to do that in this situation. Can you give me a hint in the right direction?
I certainly don't want the answer.
