## anonymous 5 years ago what it the domain of the following functions? 1. (x^2-9)/ln(x+1) 2. Sqrt(log(x+1))

not quite. the domain of log is $(0,\infty)$ so for part 1 that restriction still applies. i.e. $x+1>0$ so $x>-1$ also you cannot divide by 0 so you also have to make sure that $ln(x+1)\neq 0$ $x+1\neq 1$ $x\neq 0$ therefore domain of first one is $(-1,\infty), x\neq 0$

second one is right
