Across
  1. 2. a graph is said to be _______ if it has a negative rate of change (slope). As x increases, y decreases.
  2. 4. monomials that have the same variables to the exact same degree
  3. 7. the ______ __ _______ of a parabola opening up and down is the vertical line through the vertex
  4. 8. a function where there are y values that have more than one x value mapped to it
  5. 10. if every y value for a function has exactly one x value mapped to it
  6. 11. the composition of functions f and g, (f(g(x)) uses the output of g(x) as the input for f(x). Used to mathematically show that two functions are inverses
  7. 13. the inverse of a relation consisting of all ordered pairs (x, y) is the set of all ordered pairs (y, x). The graph of the ________ _________ is the reflection of the graph of the relation across the line y=x
  8. 14. the number that relates two variables that are directly proportional or inversely proportional to one another
  9. 16. a function of the form f(x)=b^x, where b is a positive constant other than 1 and the exponent is a variable. There is not a single parent exponential function because each choice of the base b determines a different parent function.

  11. 21. a polynomial that has exactly three unique terms
  12. 23. factors of a polynomial such that the factor is of degree 1
  13. 25. an algebraic function such that both the numerator and the denominator are polynomials and whose denominator has a degree of greater than or equal to 1

  2. 3. a solution to a polynomial equation. Also called a zero.
  3. 5. an exponential function of the form f(x)=ab^x in which 0<b<1
  4. 6. a relation in which every input (x) is paired with exactly one output (y)
  5. 9. a polynomial function of degree 5
  6. 12. a set of numbers is said to be closed, or have closure, under a given operation if the result of the operation on any two numbers in the set is also in the set
  7. 15. a graph is said to be _______ if it has a positive rate of change (slope). As x increases, y also increases.
  8. 17. values that a denominator cannot be equal to because it would make the rational expression's value not exist

  10. 20. a polynomial function of degree 4
  11. 22. a line that a graph approaches but does not intersect
  12. 24. a polynomial that has exactly two unique terms
