  1. 3. The set of all inputs (generally x-values) of a relation or function.
  2. 5. a graph that relates two different sets of data by displaying them as ordered pairs.
  3. 6. The x-coordinate(s) of the point(s) where a graph intersects the x-axis.
  4. 11. a term that has no variable
  5. 12. A measure of the steepness of a line; rise over run
  6. 13. a symbol, usually a letter, that represents one or more numbers
  7. 15. the distance that a number is from zero on a number line
  8. 16. The number being raised to a power
  9. 17. a function rule that relates each term of a sequence after the first to the term or terms before it
  10. 18. terms whose variables and their exponents are the same
  11. 20. The number that indicates how many times the base in a power is multiplied by itself
  12. 21. a word meaning "divide"
  13. 25. 1 minus the percent rate of change expressed as a decimal
  14. 26. 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.

  1. 1. In an arithmetic sequence, the nonzero constant difference of any term and the previous term.
  2. 2. A relation in which ever domain value is paired with exactly one range value.
  3. 4. in the form x = #, has undefined slope
  4. 7. 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.
  5. 8. a number that is multiplied by a variable
  6. 9. a data value that is much higher or lower than the other data values in the set
  7. 10. to find the value of an algebraic expression by substituting a number for each variable and simplifying by using the order of operations
  8. 14. a sequence of numbers where the ratio between consecutive terms is constant
  9. 19. The set of all outputs (generally y-values) of a relation or function.
  10. 22. Lines that have the same slope; they NEVER intersect
  11. 23. A ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable; slope
  12. 24. A set of ordered pairs.
  13. 27. the top number of a fraction
