If f(x) = 3x and mc010-1.jpg which expression could be used to verify that g(x) is the inverse of f(x)?

you could subsitute g(x) for x in f(x) and if you get x as a result, then that is indeed the inverse

ex
if
f(x)=x-2
the inverse which is g(x) is
g(x)=x+2 because if you did
f(g(x)) then you would get
f(g(x))=(2+x)-2=2-2+x=x
