Question

if f(x)= log {(1+x)/(1-x)} then f (x) is
a) an even function
b) an odd function
c) neither even nor odd
d) a constant term

Answer 1

no im sorry

Answer 2

the answer is C

Answer 3

i don't think so !

Answer 4

LOL

Answer 5

evaluate f(-x)

Answer 6

Someone has pretty powerful instincts :D

Answer 7

what do you think it is a constant term?

Answer 8

E its a cheese cake

Answer 9

\[\Large f(x) = \log\left(\frac{1+x}{1-x}\right)\]
Let's evaluate f(-x)
\[\Large f(\color{red}{-x}) = \log\left(\frac{1-x}{1+x}\right)\]

Answer 10

it is an odd function !

Answer 11

Which, incidentally... is...
\[\Large f(\color{red}{-x}) = \log\left(\frac{1+x}{1-x}\right)^{-1}\]

Answer 12

i didn't realize the denominator was inside the logarithm nvm

Answer 13

your tex wasn't formatted properly

Answer 14

you have powerful insticnts and you're superfast also krit ;p

Answer 15

so @terenzreignz
says
f(-x)=-f(x)

Answer 16

i have got another one !

Answer 17

okiee
