    What do you mean by "g(x)= x=6"? And which of the following do you mean?

    [tex]f(x) = \frac{1}{2x} - 7[/tex]

    [tex]f(x) = \frac{1}{2x-7}[/tex]

    [tex]f(x) = \frac{1}{2}x - 7[/tex]

    And in the future, please place threads like this in the "Precalculus Mathematics" forum of the "Homework & Coursework Questions" section.
