Question

what is the domain and the range of f(x)=1/x+1

Answer 1

get zero's of this function to get domain.
then get its inverse and get its domain thus you will get is range

Answer 2

?

Answer 3

why are you sticking with that?
domain is all numbers except which make the function undefined.

Answer 4

is it all real numbers except for 1?

Answer 5

Are you asking if the domain or range is all real numbers except for 1? And why do you think that?

Answer 6

is the domain all real numbers except for 1?

Answer 7

your function is 1/(x+1) right?
if x=1, then you have 1/(1+1)=1/2
is 1/2 not a number?

Answer 8

I think you are thinking about the opposite of 1
-1
(x+1) is what you don't want to be zero
since you can not divide by zero
and we know x+1=0 when x=-1

Answer 9

the range is kinda easy to find here too
we have 1/(x+1)

hint: we know the only thing that will ever make a fraction 0 is the top
