(4) (11 points) Solve the following initial value problem: dy da Does the solution exist for all values of r? If not, when (at what value of 2) does the solution 'blow-up'? = y²(2x-4); y(0) = -1/4 (4) (11 points) Solve the following initial value problem: dy da Does the solution exist for all values of r?
