Read each question carefully and provide the best answer. Remember that the domain refers to all possible input values (x-values) and the range refers to all possible output values (y-values) for a function.
1. The of a function is the set of all possible input values.
2. The of a function is the set of all possible output values.
3. In the coordinate pair (x, y), 'x' represents a value from the .
4. In the coordinate pair (x, y), 'y' represents a value from the .
5. Which of the following sets represents the domain of the ordered pairs {(1, 2), (3, 4), (5, 6)}?
{2, 4, 6}
{1, 3, 5}
{1, 2, 3, 4, 5, 6}
{(1, 2), (3, 4), (5, 6)}
6. What is the range of the function shown in the graph below?
All real numbers
y ≥ 0
x ≥ 0
y ≤ 0
7. Given the function y = x + 3, if the domain is {1, 2, 3, 4}, what is the range?
8. A school cafeteria serves lunch from 11:00 AM to 1:00 PM. If 't' represents the time in minutes past 11:00 AM, what is the domain for the function describing the time the cafeteria is open?
9. For the set of ordered pairs {(0, 0), (1, 1), (2, 4), (3, 9)}, the domain is {0, 1, 2, 3} and the range is {0, 1, 4, 9}.
True
False
10. In a function, each input value can have more than one output value.
True
False
