$$\huge\color{blue}{  f(z)=\frac{1}{1-z}  } $$
$$\huge\color{blue}{  g(z)=2z^2-3z  } $$

solomonzelman · Answer

To find the zeros of each function set each one equal zero and solve for z.
The y-intercept is the constant of the equation, if there is no constant then the y-intercept would be zero.

anonymous · Answer

z=x+iy---->complex-can not equate =zero----but g(z) is more easily...

solomonzelman · Answer

What? I don't understand where is the   z=x+yi   from

anonymous · Answer

ok see the solution :...

What do you mean by Re and Im parts of each functions? Is that a new mathematical concept?

anonymous · Answer

no.its about the complex numbers,real number are sublocal (i dont know what mean in english) of real numbers,and in the Cartesian shown by 2 parameter x (real part) and iy (imagery part)...

solomonzelman · Answer

Yeah, Idk that, weird but....
