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.

The slope field for the equation
y'=-x+y is shown above
On a print out of this slope field, sketch the solutions that
pass through the points
(i) (0,0);
(ii) (-3,1); and
(iii) (-1,0).
From your sketch, what is the equation of the solution to the
differential equation that passes through (-1,0)? (Verify that your
solution is correct by substituting it into the differential
equation.)
