f(x)= --- +1 Find x if f(x)=-1.
x-2

Answer 1

Plug in -1 for f(x) and find what x is.

Answer 2

\[-1 = \frac{1}{x+2} +1\]

Answer 3

f(-1)= i/(-1-2)+ 1
= -1/3 + 3 / 3 = -2/3.

Answer 4

That's not right..

Answer 5

sux, can you solve what I wrote from there?

Answer 6

I read x - 2 in the denomator, not x + 2.

Answer 7

you are right, but even so you solved for f(-1) not f(x) = -1.

Answer 8

\[-1 = \frac{1}{x-2} + 1\]

Is what needs solving for x.

Answer 9

That's so right. My misread :^)

Answer 10

Np. Now we just need mathsux to finish solving it.

Answer 11

Easily done.

Answer 12

For you perhaps, but it's not your problem ;p

Answer 13

Answer is -2 right?
