Across
- 1. function - two functions f and g are inverse if and only if both are their compositions are the identity function
- 6. - The number or expression inside a radical symbol
- 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)] .
- 10. inequality - an inequality that has a variable in the radicand
- 11. radical expressions - Two radical expressions in which both the radicands and indices are alike.
- 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.
Down
- 2. solution - A number that does not satisfy the original equation
- 3. root inequality - an inequality that contains a square root of a variable
- 4. the denominator - to eliminate radicals from a denominator or fractions from a radicand
- 5. root - The nonnegative root
- 7. - indicates to what root the value under the radicand is being taken
- 8. - binomials of the form a√b + c√d and a√b - c√d whose product is always a rational number with no radicals
