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
