If f(x) = 4x + 12, to find the inverse, reverse the actions of the elements of the function in "reverse" order.
The last thing done is "+ 12", so reverse that first by "- 12"
The previous thing done was "× 4n, so reverse that by "÷ 4", but note that the divide takes precedence over subtract, so the previous step needs to be in brackets.
Thus if the inverse of f(x) is g(x), g(x) = (x - 12) ÷ 4
