    e^(-3x) or (e^-3)*x Am assuming the former one ?

    y= C e^(-3x) works right ? y' = -3C( e^-3x) y'' = 9C(e^-3x) => 9C(e^(-3x)) - C(e^-3x) = 8(e^(-3x)) C=1 so y=e^(-3x) is a solution.

    infact, Ae^x + Ce^(-3x) can also be a soltuion.

    I am pretty sure there might be more solutions to it. Nevermind
