Graph set interval notation
WebSep 14, 2024 · Each define a direction on the number line: Infinity is not a real number. It indicates a direction. Therefore, when using interval notation, always enclose ∞ and − ∞ with parenthesis. We never enclose infinities with square bracket. The table below shows four examples of interval notation that require the use of infinity. x < 2. x ≤ 2 ... WebGiven a line graph, describe the set of values using interval notation. Identify the intervals to be included in the set by determining where the heavy line overlays the real line. At the left end of each interval, use [ with each end value to be included in the set (solid dot) or ( for each excluded end value (open dot).
