  1. 3. the point at which the graph crosses the x-axis; written as (x, 0)
  2. 5. the set of all input values (x-values) that satisfy the given function without restriction
  3. 11. where the value of the function f(x) decreases with an increase in the value of x
  4. 13. relationship between two variables in which at least one value of the domain or independent variable, x, is matched with one or more values of the dependent or range variable, y
  5. 15. the behavior of the graph as x approaches positive or negative infinity
  6. 17. a number’s distance from 0 on a number line; the positive value of a quantity
  7. 18. the least value of a function for a particular interval of the function; also known as a local minimum
  8. 19. where the value of the function f(x) increases with an increase in the value of x

  1. 1. checks if a function is one-to-one. A one-to-one function has only one x-value for each y-value. If a horizontal line passes through a graph more than once, the function can't be one-to-one.
  2. 2. the point at which the graph crosses the y-axis; written as (0, y)
  3. 4. checks if a relation is a function. A vertical line needs to cut the graph at only one point for it to represent a function. If a vertical line passes through a graph more than once, then the graph is not a function.
  4. 6. a function or operation which reverses the order or operation of another function or operation
  5. 7. the greatest value of a function for a particular interval of the function; also known as a local maximum
  6. 8. the set of all outputs of a relation or function; the set of y-values for which a function is defined
  7. 9. a set of equations with the same unknowns
  8. 10. a relation in which every element of the domain is paired with exactly one element of the range; that is, for every value of x, there is exactly one value of y
  9. 12. to determine or calculate the numerical value of (a formula, function, relation, etc)
  10. 14. a relationship wherein each point in a set of points is mapped to exactly one other point
  11. 16. a function that is defined by two or more expressions on separate portions of the domain
