@satellite73 Find the domain of definition and the range of function f(z) = 2z-5
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?
btw that either should not be there. ^
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
ok so it's all numbers lol
