<p>dunno how to do it but 18/4 isnt the answer. Graphed it on a calc and y reaches somewheres around 2 (2.136 at x = 95) Ill try do to it out after i eat something</p>
<p>3/root(2) is the answer
basicalyl al that matters is 3x and 2x^2.
negative infinity is -3/root2 because it's 3x on the top and it's rootx^2 on the bottom</p>
