Across
- 4. the four regions into which the x- and y-axis separate the coordinate plane
- 5. a relation in which each element of the domain is paired with exactly one element of the range
- 8. the set of first numbers (x-values) of the ordered pairs in a relation
- 10. a set of ordered pairs
- 11. the horizontal axis on a coordinate plane
- 12. the x-value of an ordered pair, represents the horizontal placement of the point
- 13. a formula used to find the nth term of an arithmetic sequence
- 15. the vertical axis on a coordinate plane
- 16. the set of second numbers (y-values) of the ordered pairs in a relation
- 18. the point at which the x- and y-axis intersect on the coordinate plane (0,0)
- 19. the difference (d) between consecutive terms in an arithmetic sequence
- 21. the x-intercepts of the graph of a function -- the points for which f(x) = 0
- 22. if any vertical line passes through the graph of a relation no more than once, then it is a function
Down
- 1. graph a function graphed with a line or smooth curve
- 2. the y-value of an ordered pair, represents the vertical placement of the point
- 3. a way to name a function that is defined by an equation -- replace "y" with "f(x)"
- 6. formed by the intersection of two number lines, the horizontal axis and the vertical axis
- 7. a set of numbers, or coordinates, written in the form (x, y)
- 8. a graph that consists of points that are not connected
- 9. the result of substituting a value into a function
- 14. illustrates how each element of the domain is paired with an element of the range
- 17. a numerical patterns that increases or decreases at a constant rate/value
- 20. a value substituted for an x-value in a function
