\[\boxed{\mathbf{136.}}\]

\[1)\ y = - x^{\frac{1}{2}}\]

\[x^{\frac{1}{2}} = - y\]

\[x = - y^{2}.\]

\[E(y) = ( - \infty;\ 0\rbrack.\]

\[y = x^{2}\ при\ x \leq 0.\]

\[2)\ y = - x^{\frac{3}{5}}\]

\[x^{\frac{3}{5}} = - y\]

\[x^{3} = - y^{5}\]

\[x = - y^{\frac{5}{3}}\]

\[y = - x^{\frac{5}{3}}.\]

\[3)\ y = x^{\frac{3}{2}}\]

\[x^{3} = y^{2}\]

\[x = y^{\frac{2}{3}}\]

\[y = x^{\frac{2}{3}}.\]

\[4)\ y = - x^{\frac{1}{3}}\]

\[x^{\frac{1}{3}} = - y\]

\[x = - y^{3}.\]

\[E(y) = ( - \infty;\ 0\rbrack.\]

\[y = - x^{3}\ при\ x \leq 0.\]
