____
1. A pair of numbers that can be used to locate a point on a coordinate plane
____
2. The output of a function; a variable whose value depends on the value of the
input, or independent variable
____
3. A graph made up of unconnected points
____
4. A test used to determine whether a relation is a function. If any vertical line

____
8. Each of the four regions into which the x- and y-axes divide the coordinate plane
____
9. The horizontal axis on a coordinate plane
____
10. The set of all possible input values of a function
____
11. The first number in an ordered pair; it tells the distance to move right or left
from the origin
____
12. A set of ordered pairs
____
13. Input of a function; a variable whose value determines the value of the
output, or dependent variable
____
14. The set of all possible output values of a function
____
15. The vertical axis of a coordinate plane
____
16. A plane formed by the intersection of a horizontal number line called the x-axis
and a vertical number line called the y-axis
____
17. An input-output relationship that has exactly one output for each input
