1. Find the range of each function f :

→
.

(a) f (x) = x²
+ 2

(b) f (x) = (x – 2)²
+ 4

(c) f (x) = x²
+ 6x + 4

(d) f (x) = 5 cos 4x

2. Find all possible functions f : A → B in each case below. Describe the functions by listing their ordered pairs.

(a) A = {1, 2, 3} and B = {5}

(b) A = {4} and B = {5, 6}

(c) A = {1, 2} and B = {5, 6}
