# Math Help - Implied Domain

1. ## Implied Domain

I have two questions asking about the implied domain? What is the implied domain and do you find it like you would find just a regular domain?

(a) h(x)= ln (3x - 4)

(b) h(x) = (abs(x)) / x

for b I put the implied domain I put all real numbers except 0. is this right?
i got the answer to b
this on is hard for me:

arcsin(3x -2)

for a) the implied domain for lnx x>0 so for ln (3x-4) is 3x-4>0

$1 \leq 3x \leq 3$
$\frac{1}{3} \leq x \leq 1$
