# Thread: Help with finding the domain of a function

1. ## Help with finding the domain of a function

I'm dividing these two functions:

f(x)=(x+2)/(x+5) and g(x)=(x+2)/(x+5)

So,
(x+2)/(x+5) ÷ (6x-12)/(x^2-25)

The answer I got was (- ∞,-5)∪(5,-2)∪(2,5)∪(5,∞)

Am I correct? I need it to be in interval notation please, thank you.

I am not sure , but f(X) / (gx) = 1

So I believe that the domain its all real numbers

(x+2)/(x+5) ÷ (6x-12)/(x^2-25)

I think that is >>> (- ∞,2)∪(2,∞)

I am not sure
