Solve[y == x^2, x] {{x -> -Sqrt[y]}, {x -> Sqrt[y]}} Reduce[y == x^2, x] x == -Sqrt[y] || x == Sqrt[y] Bob Hanlon ---- Arnold <sender999ster at gmail.com> wrote: ============= Function y=x^2 is given. Give, please, a code in WM-7 with which help it is possible to receive function, return the given. That is, x=g (y). Thanks.
