Across
- 2. A two-dimensional plane formed by the intersection of a horizontal number line and a vertical number line.
- 3. The set of all possible y-values (outputs) in a relation or function.
- 5. A set of ordered pairs.
- 7. A pair of numbers written in the form (x,y) that locates a point on a coordinate plane.
- 9. A diagram that shows how each element of the domain corresponds to an element of the range.
- 11. A test used to determine whether a graph represents a function. If any vertical line intersects the graph more than once, the graph is not a function.
- 13. The x-values where a function equals zero; the x-intercepts of the graph.
- 14. The second number in an ordered pair, indicating vertical position.
- 18. The four regions into which the x-axis and y-axis divide the coordinate plane.
- 19. A graph consisting of individual, unconnected points.
- 21. The constant amount added to or subtracted from each term in an arithmetic sequence.
- 22. A graph that can be drawn without lifting your pencil, consisting of connected points.
- 23. The resulting value of a function after an input is substituted.
Down
- 1. The first number in an ordered pair, indicating horizontal position.
- 4. A sequence of numbers in which the difference between consecutive terms is constant.
- 6. A way of naming a function using notation such as f(x) instead of y.
- 8. A relation in which each input is paired with exactly one output.
- 10. A formula used to find any term in an arithmetic sequence: an=a1+(n−1)d where an is the nth term, a1 is the first term, and d is the common difference.
- 12. The vertical axis on a coordinate plane.
- 15. The point where the x-axis and y-axis intersect; (0,0).
- 16. A value substituted for the independent variable, usually x, in a function.
- 17. The horizontal axis on a coordinate plane.
- 20. The set of all possible x-values (inputs) in a relation or function.
