and can you show and example

Answer 1

what is the fundamental theorem of algebra?

Answer 2

states that every non-constant single-variable polynomial with complex coefficients has at least one complex root

Answer 3

like f(x)=i*x

Answer 4

yes

Answer 5

i can't prove but as an example f(x)=ix+5
