Answer:
Domain will be x>0 or x<0 and x≠0
Step-by-step explanation:
f(x) = 3x
g(x) = 1/x
(gof)(x) = ?
(gof)(x) = g(f(x))
(gof)(x) = 1/(3x)
The domain of a function is a set of values for which the function is defined.
Find the points for which the function (gof)(x) = 1/(3x) is undefined.
if x=0 then the function is undefined.
So, domain will be x>0 or x<0 and x≠0
