    is it all complex numbers for both?

    by the way, this is a complex variables course, so it's obviously either all real numbers for both if this were on a real plane, but since this is on a complex plane, is it just all complex numbers?

    why isn't it everything? after all you can solve \(z'=2z-5\) for \(z'\) right?

    So it's all complex and real numbers?

    since z is a complex number

    well i guess u could call a real number a complex number with the imaginary part being 0.

    z = a + bi <- a - real part, bi - imaginary part
