| Question | Answer |
|---|---|
| function notation | A relation in which every input results in one and only one output f(x), g(x), h(x), k(x). |
| Radical function | f(x)= squared x |
| Radicand | the value under the square root |
| rational functions | f(x)=1/x |
| Domain(inputs) | All possible inputs (x-values) of function; values that are independent in an equation or expression |
| Denominator Restriction | domain values that render a rational expression undefined |
| square root (even root) restriction | domain values that render a square root expression undefined |
| range(outputs) | all possible outcomes(y-values) of a function; values that are dependent in an equation or expression |
| Interval notation | A way to indicate inequalities by using brackets or parentheses instead of inequality |
| U(union) | A symbol used to merge 2 or more pieces of an interval |
| Point of discontinuity | An X-value on the graph where the y-value is undefined |
