For the function $f(x)$ given below, evaluate $\underset{x}{lim}f(x)$ and $\underset{x}{lim}f(x).$

$f(x)=\frac{2e^{x}3}{4e^{x}2}$

If the function increases without bound, you should enter $.$ If the function decreases without bound, you should enter $-.$ If the function does not appraach a finite limit nor $-$ as $x-,$ you Should enter DNE.
