Answer 1

Hey guys. I need help finding the domain of function x+4/x+3

Answer 2

Answer 3

Being as domain should be all possible x values, the domain would be any number except -3, as that would make the bottom equal 0, which is undefined. This means the domain is (-infinity,-3) U (-3,infinity), which is all real numbers except -3.

Answer 4

is that
f(x) = (x + 4) / (x + 3)

Answer 5

Thank you very much @1davey29 :)

Answer 6

or as you wrote it...

\[f(x)=x+\frac{ 4 }{ x }+3\]

Answer 7

Actually that was wrong :( it was [-4,-3)U(-3, infinity)

Answer 8

Sorry about that. Forgot it would stop being a function after -4.
