Do you mean *[tex \LARGE x^2\ +\ \frac{1}{2x}\ -\ 5]


Or *[tex \LARGE \frac{x^2\ +\ 1}{2x}\ -\ 5]


Or *[tex \LARGE \frac{x^2\ +\ 1}{2x\ -\ 5}]


Re-post using sufficient parentheses to make it clear what terms are in the numerator of your rational expression and what terms are in the denominator.  See &lt;a href=&quot;http://www.purplemath.com/modules/mathtext.htm&quot;&gt;Formatting Math as Text&lt;/a&gt; if you are having difficulty rendering mathematical expressions in plain text.


Meanwhile, *[tex \LARGE \exists\,f^{-1}\ \Rightarrow\ \text{rng}\left(f^{-1}\right)\ \equiv\ \text{dom}\left(f\right)]
