Hoot! You just asked your first question! Hang tight while I find people to answer it for you. You can thank people who give you good answers by clicking the 'Good Answer' button on the right!

Answer 2

the domain is R-{1}. at x=1 the equation is not defined and hence its not a part of the domain .

Answer 3

got it?

Answer 4

still think==

Answer 5

then if f(x)=1/x, what is the domain?

Answer 6

if f(x) =1/x then domain is R- {0} for a function denominator is never equal to 0..

Answer 7

shankvee is rite.
look, for finding the domain, u actually find those values for which the function is not defined and then exclude it from the real value set R.

Answer 8

oooo.. i see... thanks!!!
