Relations and Functions Vocabulary

4. a graph of points that are all connected
5. a relation in which each element of the domain (x value)is paired with exactly one element of the range (y-value)
9. formed by the intersection of two number lines, the horizontal axis and vertical axis
12. the set of the x-values of the ordered pairs in a relation, the left and right boundaries of a graph
15. the x-intercepts of the graph of a function. The points for which f(x) = 0.
16. the point at which the x and y axis intersect on the coordinate plane; (0,0)
20. if any vertical line passes through the graph of a relation no more than once, then the graph is a function
22. the vertical axis on a coordinate plane
23. the four regions into which the x- and y- axis separate the coordinate plane.

1. the x-value of an ordered pair, represents the horizontal placement of the point
2. Illustrates how each element of the domain is pair with an element of the range, represented by two ovals containing the x values in the first and y values in the second.
3. A formula use the find the nth term of an arithmetic sequence. a_n=a_1+d(n-1)
6. the difference (d) between consecutive terms in an arithmetic sequence
7. The y-value of an ordered pair, represents the vertical placement of the point
8. the horizontal axis on a coordinate plane
10. a numerical pattern that increases or decreases by a constant value.
11. a way to name a function that is defined by an equation. Replace "y" with "f(x)" (read as "f of x")
13. - A set of numbers or coordinates written in the form (x,y) that represent a point on the coordinate plane.
14. - a graph that consists of points that are not connected
17. a set of ordered pairs
18. the result of substituting a value into a function. It is the calculated value.
19. the set of y-values of the ordered pairs in a relation, the ceiling and floor (top and bottom) boundaries of a graph
21. a value substituted for an x-value in a function.
