Question

Find the inverse of the function.
f(x)=(3/-x-3)+1
(the 3 is actually over the -x-3)

Answer 1

\[f(x)=\frac{3}{-x-3}+1\]?

Answer 2

you can start by writing
\[x=\frac{3}{-y-3}+1\] and solve for \(y\)

Answer 3

any idea how to do that?

Answer 4

No, that first step is what I thought I needed to do but I haven't touched this material in 8 months.

Answer 5

you can do a few different things
a good first step might be to subtract 1 from both sides, get
\[x-1=\frac{3}{-y-3}\]
then flip and and get
\[\frac{3}{x-1}=-y-3\]

Answer 6

add 3 and then change the sign to finish

Answer 7

oh, ok. Thanks so much =)
