STEP 1: Plug g\left ( x … WebTo prove that g is the inverse of f we must show that this is true for any value of x in the domain of f. In other words, g must take f (x) back to x for all values of x in the domain of f. So, g (f (x)) = x must hold for all x in the domain of f. The way to check this condition is to see that the formula for g (f (x)) simplifies to x.
