  1. 1. The set of all outputs (generally y-values) of a relation or function.
  2. 5. the intersection of the x- and y-axes in a coordinate plane
  3. 9. The x-coordinate(s) of the point(s) where a graph intersects the x-axis.
  4. 10. The number that indicates how many times the base in a power is multiplied by itself
  5. 11. 1 minus the percent rate of change expressed as a decimal
  6. 12. a sequence of numbers where the ratio between consecutive terms is constant
  7. 13. The number being raised to a power
  8. 15. A function that can be written in the form y=mx+b, where x is the independent variable and m and b are real numbers. Its graph is a line.
  9. 19. a graph that relates two different sets of data by displaying them as ordered pairs.
  10. 20. to find the value of an algebraic expression by substituting a number for each variable and simplifying by using the order of operations
  11. 21. a function rule that relates each term of a sequence after the first to the term or terms before it
  12. 22. A ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable; slope
  13. 25. the distance that a number is from zero on a number line
  14. 26. a data value that is much higher or lower than the other data values in the set
  15. 28. in the form x = #, has undefined slope
  16. 29. The set of all inputs (generally x-values) of a relation or function.
Down
  1. 2. the top number of a fraction
  2. 3. A relation in which ever domain value is paired with exactly one range value.
  3. 4. terms whose variables and their exponents are the same
  4. 5. a process for evaluating expressions, PEMDAS
  5. 6. a number that is multiplied by a variable
  6. 7. In an arithmetic sequence, the nonzero constant difference of any term and the previous term.
  7. 8. a sequence of numbers where the difference between consecutive terms is constant
  8. 14. a term that has no variable
  9. 16. A set of ordered pairs.
  10. 17. An exponential function in the form y=a(1+r)^t, where r is the rate of growth, a is the initial amount and t is the time.
  11. 18. A measure of the steepness of a line; rise over run
  12. 23. Lines that have the same slope; they NEVER intersect
  13. 24. a symbol, usually a letter, that represents one or more numbers
  14. 27. a word meaning "divide"
