    g(x) = √15-4 is just a constant. there's no domain to input

    {X = all real numbers, 15/4 < X < infinity}

    whoops i mean [15/4, infinity) since you can have 0 under radical

    \[15/4 \le X < \infty\]

    i would just put that into brackets then right? like {X = all real numbers, 15/4 < X < ∞}

    yeah but it's 15/4 ≤ X < ∞
