Question

find the inverse of f(x)=(x+1)/(x-1)

Answer 1

(x+1)/(x-1)

Answer 2

the same?....why?....wolfram suggests that too but it doesnt make sense :S

Answer 3

well check it out.....try substituting some value......

Answer 4

so if the inverse is the same...there is no inverse...the function is one to one or not?

Answer 5

lol no...it is bijective......the inverse is same.....jus it is a funny case :P

Answer 6

bijective?

Answer 7

um ok it s one one...sry not bijective

Answer 8

so it is one to one but its inverse is the same as the original...thats absurd!

Answer 9

lol no.....dont get so confused.....that's not absurd...no rule that inverse should nt be the same as the function....nd wat do u say about f(x) = x

Answer 10

aha...thank you very much dude!

Answer 11

not a prob :)
