what this means is replace 'x' in the G(x) function with (2x/x3) its domain is what values of x would Gf(x) be real for. i.e. when the bottom part of the fraction does not equal zero

How often, in the real adult world, is this stuff really actually used?

(gof)x = g(f(x)) = 3/f(x) = 3/(2x/x3) = 3x9/2x domain  all numbers except 0
