  1. 6. This is the variable that affects the dependent variable; it usually associated with x
  2. 8. the value that’s multiplied in a geometric sequence
  3. 10. the point where a function crosses the y-axis. The x-value at this coordinate point will always be 0.
  4. 11. the values that result from inputs going into a function; the dependent variable
  5. 16. A function whose graph is one, smooth line or curve; the graph does not have any breaks
  6. 17. all numbers 0 or greater that don’t include decimal parts
  7. 18. all whole numbers and their negatives (ex: -4, 5, 134)
  8. 22. a function in which the independent variable (x-value) is the exponent to a base (ex: y=7x)
  9. 25. An exponential function that goes up due to a base value > 1
  10. 26. a function that has distinct and separate values; the function values are not connected by lines
  11. 27. the point where a function crosses the y-axis. The y-value at the coordinate point will always be 0.
  12. 28. An exponential function that goes down due to a base value < 1
Down
  1. 1. an equation that lets you find any term (the nth term) in a function
  2. 2. the constant rate of change in a linear function; “rise over run” or “change in y divided by change in x”
  3. 3. a relation that says a set of inputs that each have one output (x is generally the input, and y = f(x) is generally the output)
  4. 4. Functions that have a maximum degree (highest exponent) of 1 (ex: y=mx+b); these functions graph straight lines
  5. 5. this is the number that gets raised to an exponent; it is the number that gets multiplied over and over
  6. 7. Any number that can be expressed as a ratio (fraction). For example, ⅓ , 7.2, 5, -6, 5/7
  7. 9. an equation that uses the previous term to find the next term
  8. 12. the set of all values for the dependent variable (the y variable)
  9. 13. This means to get a value from substituting in a number to a function. (ex: if f(x) = 3x-1, then “evaluate f(5)” means put 5 into f(x): f(5) = 3(5) - 1 = 14).
  10. 14. all possible values for the independent variable (x-values)
  11. 15. a sequence in which each next term is obtained by multiplying the previous term by a common ratio
  12. 19. the value that’s added in an arithmetic sequence
  13. 20. A list of numbers that has a common difference between terms
  14. 21. The variable that changes as another value changes; usually associated with “y” or “f(x)”
  15. 23. the x-values that go into a function the values for the independent variable
  16. 24. the number that shows how many times you multiply a base (ex: in 49, what is the 9 called?)
