  1. 1. function - two functions f and g are inverse if and only if both are their compositions are the identity function
  2. 6. - The number or expression inside a radical symbol
  3. 9. of functions - A function is performed, and then a second function is performed on the result of the first function. The composition of f and g is denoted by f ◦ g, and [f ◦ g](x) = f[g(x)] .
  4. 10. inequality - an inequality that has a variable in the radicand
  5. 11. radical expressions - Two radical expressions in which both the radicands and indices are alike.
  6. 12. root - For any real numbers A and B, and any positive integer N, if A'N = B, then A is an Nth root of B.

  1. 2. solution - A number that does not satisfy the original equation
  2. 3. root inequality - an inequality that contains a square root of a variable
  3. 4. the denominator - to eliminate radicals from a denominator or fractions from a radicand
  4. 5. root - The nonnegative root
  5. 7. - indicates to what root the value under the radicand is being taken
  6. 8. - binomials of the form a√b + c√d and a√b - c√d whose product is always a rational number with no radicals
