    Step-by-step explanation:

    Firstly, we need to be very clear and use brackets.

    I assume you mean g(x) = (2x + 3)/(x – 4)…??

    There is a ‘world’ of difference between this and other forms…

    i.e. g(x) = 2x + (3/x) – 4 or 2x + (3/(x – 4)

    Assuming the former we have a rational function, which will exist so long as the denominator is NOT zero.

    i.e. x – 4 ≠ 0

    so, x ≠ 4

    Hence, g(x) does not exist if x = 4

    plz mark me as a brain list and follow me..
