1. Geometrically, the image of f(z) = 2 + i is

(a) a point   ; (b) a line   ; (c) a disk   .

2. Geometrically, mapping f(z) = maps the square with vertices (1, i) onto itself.

(a) True   ; (b) False   .

3. If u + iv u₀ + iv₀, then we must have u u₀.

(a) True   ; (b) False   .

4. If f(z) = 2 + i and g(z) = 2 - i then (f.g)(z) = 5.

(a) True   ; (b) False   .
