Across
  1. 4. the four regions into which the x- and y-axis separate the coordinate plane
  2. 5. a relation in which each element of the domain is paired with exactly one element of the range
  3. 8. the set of first numbers (x-values) of the ordered pairs in a relation
  4. 10. a set of ordered pairs
  5. 11. the horizontal axis on a coordinate plane
  6. 12. the x-value of an ordered pair, represents the horizontal placement of the point
  7. 13. a formula used to find the nth term of an arithmetic sequence

Down
  1. 1. graph a function graphed with a line or smooth curve
  2. 2. the y-value of an ordered pair, represents the vertical placement of the point
  3. 3. a way to name a function that is defined by an equation -- replace "y" with "f(x)"
  4. 6. formed by the intersection of two number lines, the horizontal axis and the vertical axis
