Answer:

The three iterates are:

  • z_1=8i+3
  • z_2=14i+9
  • z_3=26i+21

Step-by-step explanation:

We are asked to find the first three iterates of the function:

f(z) =2z+(3-2i) with an initial value:

z_0=5i

The first iterate is:

z_1=f(z_0)=2z_0+(3-2i)\\\\z_1=2\times 5i+3-2i\\\\z_1=10i-2i+3\\\\z_1=8i+3

Now, the second iterate is:

z_2=f(z_1)=2z_1+(3-2i)\\\\z_2=2\times (8i+3)+3-2i\\\\z_2=16i+6+3-2i\\\\z_2=14i+9

Third iterate is:

z_3=f(z_2)=2z_2+(3-2i)\\\\z_3=2\times (14i+9)+3-2i\\\\z_3=28i+18+3-2i\\\\z_3=26i+21
