Question

find the inverse of f(x) square root of 2/x-1 -1

Answer 1

\[\sqrt{2/x-1}\] -1

Answer 2

halaaa, xD ezek

Answer 3

hahha di ko alam ung square root of 2 -1

Answer 4

cross multiply lng yan

Answer 5

@terenzreignz , patulong naman oh, xD

Answer 6

\[\Large \color{blue}y = \sqrt{\frac2{\color{red}x} - 1}\]

Answer 7

teka, hindi naman sayo to ah...

Answer 8

ahahah, xD \[\sqrt{\frac{ 2 }{ x }-1} -1\]

Answer 9

schoolmate yan , xD

Answer 10

\[\Large \color{blue}y = \sqrt{\frac2{\color{red}x} - 1}-1\]

Answer 11

tamaa

Answer 12

o... kaya mo na yan :P

Answer 13

awtzsmm i square both sides??

Answer 14

Sandali lang.
pagpalitin mo muna yung x at y.
\[\Large \color{red}x = \sqrt{\frac2{\color{blue}y} - 1}-1\]

Answer 15

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

Answer 16

@Faye281
¿Donde estás?

Answer 17

hui!! sinu ka daw..

Answer 18

*nasan pala ahah

Answer 19

aha mali... :P
Wag mong pahirapan sarili mo... ilipat mo muna yung +1 sa kabila...
\[\Large \color{red}x = \sqrt{\frac2{\color{blue}y} - 1}\boxed{-1}\]

Answer 20

tapos??

Answer 21

mahirap kasi magtype, mabagal ako ehh

Answer 22

tapos... ilipat mo nga sabi... -.-
\[\Large \color{red}x+1 = \sqrt{\frac2{\color{blue}y} - 1}\]

Answer 23

yes, you squared both sides, but...
you squared incorrectly.
\[\Large \left[\sqrt{\frac2{\color{blue}y} - 1}-1\right]^2 \ne \frac2y -1 - 1\]

Answer 24

continue?

Answer 25

magparamdam ka... -.-

Answer 26

ayos...

Answer 27

\[\Large \color{red}x+1 = \sqrt{\frac2{\color{blue}y} - 1}\]

From here, you can square both sides to yield
\[\Large (\color{red}x+1)^2 = {\frac2{\color{blue}y} - 1}\]
Yes?

Answer 28

yup,,

Answer 29

(Ateneo mode)
Okay, well, you know, you make lipat the -1 to the other side, like this oh...
\[\Large (\color{red}x+1)^2 +1= {\frac2{\color{blue}y} }\]

Answer 30

yaaah

Answer 31

di pa ito tapos ah....

Answer 32

ou, xDDD

Answer 33

And then... you can get the reciprocal of both sides...
\[\Large \frac1{(\color{red}x+1)^2+1}=\frac{\color{blue}y}{2}\]

Answer 34

And multiply both sides by 2...
\[\Large \frac2{(\color{red}x+1)^2+1}=\color{blue}y\]

et voila :P
