Consider the part of the graph of $y ^ { 2 } + x ^ { 3 } = 15 x y$ that is strictly to the right of the $Y$-axis, i.e., take only the points on the graph with $x > 0$.
\textbf{Questions}
(33) Write the least possible value of $y$ among considered points. If there is no such real number, write NONE.\\
(34) Write the largest possible value of $y$ among considered points. If there is no such real number, write NONE.
