    \[\sqrt {2}=2^{\frac {1}{2}}\]\ Radical and Exponential forms, respectively.

    radical being the root and exponential being the 1/2 i presume.

    Correct. Did you have other questions about ratios and exponents?

    do you know \[f^-1(x)\] problems?

    Like this? \[f^{-1}(x) = ????\]

    exactly! i know it has to do with inverse functions with switching x and y.

    but the way she presented it was in aa long word problem.

    Sounds like generally you know how to find the inverses of a function. { from ::: http://www.uncwil.edu/courses/mat111hb/functions/inverse/inverse.html ::: Steps for finding the inverse of a function f. Replace f(x) by y in the equation describing the function. Interchange x and y. In other words, replace every x by a y and vice versa. Solve for y. Replace y by f-1(x). }}} It would seem that you just need to find a way to parse the word problem into your first equation. Once you have that you can then find the inverse as usual - I would imagine.

    Good luck. Also the Purplemath pages seem pretty good. (revealed after googling: 'inverse of a function'. Good Luck!
