WebOpen circles are used for numbers that are less than or greater than (< or >). Closed circles are used for numbers that are less than or equal to and greater than or equal to (≤ or ≥). For... WebThe Domain (all the values that can go into the function) is all Real Numbers up to and including 6, which we can write like this: Dom (f) = (-∞, 6] (using Interval Notation) Dom (f) = {x x ≤ 6} (using Set Builder Notation) And here are some example values: Example: Here is another piecewise function: which looks like: What is h (−1)?
