Practice for Analytic View of Invertible Functions.
How You Can (And Should) Get More Practice!
Below is a few practice problems of various difficulty, but you will need considerably more practice than one each. For that reason
you should definitely use the green “Try Another” button in the top right corner at least two or three times to complete
additional versions of these questions for more practice. You should keep using that button until doing these problems feels straight
forward and easy, and then come back after a week or so of doing other stuff and try again to make sure it is still just as easy for
you.
Find the inverse for the function .
Recall; to find an inverse analytically you can switch the input/output variables (replace “” with “” first) and then re-solve
for . Alternatively you can just solve the original expression for . In order to undo a power, use the associated root, and for the love
of God don’t expand any of these polynomials or you will go insane!
