    Uhm... I think it might be -9-e^{3t} in the first box, -(-9-e^{3t})-1 in the second, -(-1)-1 in the third and -(-1)+3\cos(-9t) in the last one. Not sure though...
    If this is for WebWork, you could try these. If you have unlimited tries that is.

    Obviously f_1(t)=-9-e^{3t} goes in the first box, then what goes in the (n+1) th box is: f_{n+1}(t)=-f_n(t)+g_{n+1}(t) where g_n(t) is the function in the n th part of the function definition, so:

    g_1(t)=)=-9-e^{3t}

    g_2(t)=-1

    g_3(t)=-1

    g_4(t)=3 \cos(-9t)
