Main Question or Discussion Point

dy(t)/dt= c1* y(t) + 1 - c2*f(c3*y(t))

Here c1>0, c2 is a complex number but |c2|<=1, c3>0,

f(c3*y(t)) is a nonlinear function of c3*y(t).

The initial value is given by y(s)=0.

Is it possible to be solved?

I think that any solution will be highly dependant on the function f(c3*y(t)), and in most cases there will probably be no anylitic solution to the equation.

what about an exponential for the "f" function?

Since your DE admit separation of variables, the solution of your DE (in implicite form) with your initial value is as follows

t-s-\int_0^{y(t)}\frac{dz}{zc1+1-c2f(zc3)}=0 .
