(1 point) Find the general solution to the homogeneous differential equation d'y dy + 6 + 9y = 0 dt? dt The solution can be written in the form y = Cifi(t) + C2f2(t) with fi (t) = and fa(t) = Left to your own devices, you will probably write down the correct answers, but in case you want to quibble, enter your answers so that the functions are normalized with fi (0) = 1 and f2(0) = 0.
