    if you meant to have (x^2 + 25) as the whole denominator, then the domain is all real numbers cause x^2 + 25 will never equal zero. If the +25 was not part of the denominator then x^2 is zero when x=0, so the domain would be all real numbers excluding 0, cause 0 would make the function undefined.

    g(x) = 5x/(x^2 + 25)

    (x ∈ ℜ)
