2. What is the range of the function [pic] if the domain is {4, 5, 6}?
3. If [pic], find the value of y for each value of x.
(a) 0 (b) 3 (c) -2 (d) 0.1
4. Ordered Pairs:
(a) {(1, 6), (2, 4), (3, 6), (4, 8)} (b) {(-1, 0), (-1, 3), (1, 0), (1, 3)}
DOMAIN = DOMAIN =
RANGE = RANGE =
FUNCTION = ( Yes / No) FUNCTION = ( Yes / No)
5. Table of values:
|[pic] |-3 |-2 |-1 |0 |1 |
|[pic] |-6 |-4 |-2 |0 |2 |
DOMAIN =
RANGE =
FUNCTION = ( Yes / No)
