1.Find a function f(z) such that the line below is the graph of the equation |z-3i|=|f(z)|. z is a complex number in the form a+bi in all 3 questions

2.The square of the non-real complex number z is equal to the z (this z should have a line on top of it) . What is the real part of z? (the answer is not 1/4 btw)

3. Evaluate the absolute value of (1/2)-(3/8)i
