  1. 4. measurements that have different units. For our movie example, the run-times are given in hours, minutes, and seconds, so they are
  2. 7. A relation in which no x-coordinate appears in more than one (x,y) ordered pair. Output
  3. 9. The set of outputs (y-coordinates) of a relation or function.
  4. 11. In mathematics, an nth root of a number x is a number r which, when raised to the power n, yields x: {\displaystyle r^{n}=x, } where n is a positive integer, sometimes called the degree of the root.
  5. 14. A letter (like x) that we can use to mean different numbers at different times.
  6. 15. is a function that satisfies the two properties.
  7. 16. A point where a curve meets the horizontal axis (the x-axis).
  8. 18. algebraic expressions consist of variables and coefficients. Variables are also sometimes called indeterminates.
  9. 19. is used to multiply binomials. FOIL is an acronym. The letters stand for First, Outside, Inside, and Last
  10. 20. In power, the number of times the base is multiplied by itself.

  1. 1. The set of inputs (x-coordinates) of a relation or function.
  2. 2. a mathematical expression consisting of two terms connected by a plus sign or minus sign.
  3. 3. A point where a line or curve meets the vertical axis (the y-axis). X-Intercept
  4. 5. is a number that is not a fraction; a whole number.
  5. 6. is a mathematical expression in which the sides are not equal. compares any two values and shows that one value is less than, greater than, or equal to the value on the other side of the equation.
  6. 8. is a finite combination of symbols well-formed according to rules that depend on the context. Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help get the ermine order of operations and other aspects of logical syntax.
  7. 10. involves the second and no higher power of an unknown quantity or variable.
  8. 12. is a numerical or constant quantity placed before and multiplied by the variable in an algebraic expression (e.g. 4 in 4x y).
  9. 13. a number that describes the line's direction and steepness. often denoted by the letter m; there is no clear answer to why the letter m is used.
  10. 17. is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
