  1. 2. The set of all possible input values x for a function
  2. 4. A function that "undoes" the action of another function. It has a special symbol that is NOT a negative number
  3. 5. A logarithm (ln) with base e where e is approximately 2.718
  4. 6. The exponent to which a base must be raised to produce a given number; the inverse of an exponential function
  5. 7. A process where a quantity increases at a rate proportional to its current value
  6. 13. A sequence where each term is found by multiplying the previous term by a constant common ratio
  7. 15. The expression under a radical symbol
  8. 16. The maximum or minimum point of a parabola; the point where the graph changes direction written x = #
  9. 19. A line that a graph approaches but NEVER touches (horizontal, vertical, or oblique)
  10. 22. The behavior of the graph of a function as x approaches negative and/or positive infinity
  11. 23. A solution derived from an equation that does not satisfy the original equation
  12. 24. A sequence where each term is found by adding a constant common difference to the previous term
  13. 25. The set of all possible output values y for a function
  14. 26. The highest exponent found in a polynomial expression
Down
  1. 1. An x value where the function y = 0 on the x axis. Also called a root or x-intercept
  2. 2. The value of the expression from the quadratic formula, used to determine the number (zero, one, two) and type of solutions (real or imaginary)
  3. 3. A relation where each element of the domain is paired with exactly one element of the range
  4. 8. A process where a quantity decreases at a rate proportional to its current value
  5. 9. The coefficient of the term with the highest degree
  6. 10. A probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence
  7. 11. The distance a number is from zero on a number line
  8. 12. Theorem If a polynomial P(x) is divided by (x-c) the remainder is P(c)
  9. 14. A measure of how spread out the numbers in a data set are from the mean
  10. 17. The vertical line that passes through the vertex and divides the parabola into two matching halves
  11. 18. A logarithm with base 10
  12. 20. Function The simplest function in a family of functions linear, absolute value, square, square root, cube, cube root, exponential, logarithmic, constant, rational, rational inverse and piecewise
  13. 21. Notation A way to describe continuous sets of real numbers using parentheses for non-inclusive and brackets for inclusive boundaries
