If the composition of two functions is:
1/x-3

what would be the domain restriction? describe how you found that answer.
[no answer choices]
i'm pretty sure the answer would be x≠3, because typically in these scenarios, anything the x on the bottom is being subtracted by has that symbol and the number being subtracted from it. i believe this is because x is = to 3, meaning that - 3 would make it 0 again. thus, x≠3. but if this isn't true, i'd like someone else to explain it to me, and provide me with the correct answer.
