Could you please check my answers and help me with one?
Find the domain of the function.
-I got the domain being (negative infinity, postive infinity).
g(x)= 3x/x^2 -49 (This one I don't understand how to find the domain)
yes on domain
I assume the second is g(x)=3x/(x^2-49)
can x be +-7 ?
I try to figure out it, and since x^2-7 is a perfect square (x+7)(x-7), I thought x couldn't be +-7?
