  1. 4. The cube root of a number is a special value that, when used in a multiplication three times, gives that number.
  2. 7. A line that a curve approaches as it heads towards infinity.
  3. 10. a function or operation which reverses the order or operation of another function or operation
  4. 12. exponents that are fractions, where the numerator is a power and the denominator is a root.
  5. 14. the smaller number that is placed at the top left of the radical symbol
  6. 15. The value inside the radical symbol. The value you want to take the root of.
  7. 16. A square root, cube root, etc. The symbol is √
  8. 17. a mathematical function that involves finding the value that, when multiplied by itself three times, equals a given number. In other words, the cube root of a number is the value that, when cubed, gives that number.

  1. 1. The square root of a number 𝑥, is a number, 𝑦 such that 𝑦^2 = 𝑥; in other words, the square root of a number is a number whose square is 𝑦 ∙ 𝑦.
  2. 2. a solution to an equation
  3. 3. solutions A solution to an equation that SEEMS to be right, but when we check it (by substituting it into the original equation) we find it is NOT right.
  4. 5. A symbol written above and to the right of a mathematical expression to indicate the how many times the mathematical expression (base) should be multiplied by itself.
  5. 6. (√ )used to denote square root or nth roots.
  6. 8. number A number that cannot be represented as a fraction. A number like pi is irrational because it contains an infinite number of digits with no discernable pattern. In the diagram below, you can see an example of some rational and some irrational numbers
  7. 9. a function with a radical around the x variable.
  8. 11. describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).
  9. 13. expression an expression containing a square root
