yes on domain
I assume the second is g(x)=3x/(x^2-49)
can x be +-7 ?
Could you please check my answers and help me with one?
Find the domain of the function.
f(x)=-8x-2
-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)
