WebSep 12, 2016 · You would say f(x)=2x, so 2x=4 and you would solve the equation finding x=2. Check it: f(2)=2*2=4. Looking for an x value that gives the output value f(x) is called inverting. It is convenient to introduce a letter to hold the output. For instance, f(x)=y. We say the inverse function is the one that takes y-values and gives back x-values.
