Problem 1. (2.20.2) Find $f'(z)$ for the following functions. 1. $f(z) = 3z^2 - 2z + 4$; 2. $f(z) = (2z^2 + i)^5$; 3. $f(z) = \frac{z-1}{2z+1}$, $z \neq -\frac{1}{2}$.

Step 1
For the function f(z) = 3z^2 - 2z + 4, we can simply substitute any value of z into the equation to find f(z). For example, if we substitute z = 2, we have: f(2) = 3(2)^2 - 2(2) + 4 = 3(4) - 4 + 4 = 12 - 4 + 4 = 12 So, f(2) = 12. Show more…
