Across
- 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.
Down
- 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.
