Question 5. (4 marks) Consider the first order differential equation y' = x² + y2 subject to the condition y(0) = 0. As discussed in lectures, the solution to this problem for x > 0 has a vertical asymptote. Use the transformation Y u to transform the above differential equation into a second-order linear homogeneous equation. Determine equivalent initial conditions for this transformed equation, and identify what the transformation implies about solutions to the original equation, y.
