Question

How to find the inverse of
y=1/x+1

Answer 1

is this
\[y = \frac{ 1 }{ x + 1 }\]

or

\[y = \frac{ 1 }{ x } + 1\]

?

Answer 2

the first one

Answer 3

to find the inverse, swap the variables:

\[x = \frac{ 1 }{ y + 1 }\]

then solve for y

Answer 4

i know, but would I divide by 1 then take away the positive one from each side?

Answer 5

well first you would interchange (y + 1) with x to get

\[y + 1 = \frac{ 1 }{ x }\]

Answer 6

oh ok.

thanks
