![]() Obtain f(x) = (x-2) 2+2, then inversing it so that you get f -1(x) = 2-sqrt(x-2). Now, that last example is not to be said it can't be done, but it involves completing the square to Know what you did to x because you did it to twoĭifferent x's and you didn't do the same thing to both of The independent variable in the function? You don't What happens when there is more than one occurrence of The original function, it wouldn't have had anĮxample 3 The function f(x) = x 2 - 4x + 6, x≤2 Since y must be at least 3, we need the positive square root and not the negative. That means that for the inverse, the range is y≥3. Now we go back to the original domain of x≥3. That's because of the ± that appeared when we took the square root of both sides.
