    solve x = (-8 - 8y)^{1/4} for y, you'll get
    y = h^{-1}(x) = . . .,
    then h^{-1}(-1) =

    In order to get inverse functions you can solve for x in the original equation and then switch x and y, or first switch x and y and then solve.

    This is the original equation...

    y = \sqrt[4]{-8-8x} and  x\leq -1
