Find The Domain
f(x)=log(15-x)
ANSWER IN INTERVAL NOTATION (x,y)
@Mathematics

Answer 1

guess the last answer didn't make sense. x has to be less than 15.

Answer 2

i think the answer would be:
\[x \in (-\infty, 0)\]

Answer 3

it would be if it was the domain of
\[\ln(-x)\] but since it is the domain of
\[\ln(15-x)\] it is not
\[(-\infty,0)\]

Answer 4

you're right, silly mistake, so it would be
\[x \in(-\infty, 15)\]
i hope i got it right this time
