Question

give the domain for the function f (x) = y-3
                                                             ____
                                                             y+5y-6

anonymous · Answer

all real except -6 and 1

anonymous · Answer

wait is the y on the bottom supposed to be squared?

anonymous · Answer

no, just y

anonymous · Answer

so it's $$y+5y-6$$

anonymous · Answer

yes

anonymous · Answer

in other words it's 6y -6

anonymous · Answer

if you pull out the 6 you'll get 6(y-1)

anonymous · Answer

the domain is defined a all real number except when the domain = 0 as it would be undefined

anonymous · Answer

so it's undefined when y = 1

anonymous · Answer

$$[\infty,1)\cup(1,\infty]$$

anonymous · Answer

ohh, thank you!

anonymous · Answer

your book probably has a D in front of what my answer is above for Domain

anonymous · Answer

yash check it , it's been about a year since i've taken a math class lol

anonymous · Answer

hey its f(x)=something variable in y
so is it true???
i'm having a doubt..:\

anonymous · Answer

that's true idk why it's like that

anonymous · Answer

maybe she mean't f(y)

anonymous · Answer

yeah thats what i'm trying to say

anonymous · Answer

It says in the equation f(x)

anonymous · Answer

or her teacher wasn't thinking when he gave her the question

anonymous · Answer

:P
yeah...lolzzz..:p

anonymous · Answer

i think that's the answer the teacher wants otherwise the domain could be anything i think ll

anonymous · Answer

yeah u r right 
hey @outkast please help me with my question too
please

anonymous · Answer

so if you add y+5y-6 then it would be undefined? i'm so lost :-/

anonymous · Answer

no,we were not talking about that
actually u wrote f(x)= something variable in y
so acc. to that answer can be anything
and if it is f(y)= variable fxn in y then his answer is correct..:)
