What am I missing?

1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
2. Wait patiently for a helper to come along.
3. Once someone helps you, say thank you and close the thread with:

   +close
   

4. Feel free to nominate the person for helper of the week in #helper-nominations
5. Do not ping the mods, unless someone is breaking the rules. If there is a conflict amongst multiple helpers feel free to ping “Helper Mod”
6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

because when you “plug in” infinity, you get $\lim_{x\to\infty} 4x-x\cdot\sqrt{16}$

(notice i am able to omit the absolute value because x is approaching positive infinity)

[dim jay]

Yes but don't you still get 4x - 4x, where x approaches infinity, making the whole thing approach 0?
