@satellite73 Find the domain of definition and the range of function
f(z) = 2z-5

bahrom7893 · Answer

is it all complex numbers for both?

bahrom7893 · Answer

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?

bahrom7893 · Answer

btw that either should not be there. ^

anonymous · Answer

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

bahrom7893 · Answer

So it's all complex and real numbers?

bahrom7893 · Answer

since z is a complex number

bahrom7893 · Answer

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

bahrom7893 · Answer

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

bahrom7893 · Answer

ok so it's all numbers lol
