    \[f(x)=\frac{\sqrt{x+8}}{(x+4)(x-6)}\]

    I'm not sure either, it was given to me written out but I would assume that looks correct

    so look, can't take the square root of a negative right? so for sure \(x+8\geq 0\)

    that means \(x\geq -8\) also the denominator can't be zero either because that would make it not a number
