WebSep 5, 2024 · We use interval notation to describe the interval. Interval notation has the form [\(a,b\)], which means the interval begins at \(a\) and ends at \(b\). In the example, the notation [\(0, \pi\)] has the same meaning as \(0 \leq \theta \leq \pi\). ... all values in the interval [-1,1]. Correct. The graph of the function extends forever in both ... WebUsing Interval Notation Indicating the solution to an inequality such as x ≥ 4 can be achieved in several ways. We can use a number line as shown in Figure 2. The blue ray begins at x = 4 and, as indicated by the arrowhead, continues to infinity, which illustrates that the solution set includes all real numbers greater than or equal to 4. Figure 2

WebSep 12, 2024 · Sketch the solution on the real line, then use interval notation to describe your solution. Solution To “undo” subtracting , we add to both sides of the inequality. To shade the real numbers less than or equal to , we shade the number and all real numbers to the left of . Using interval notation, the solution is . 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). WebThe third method is interval notation, in which solution sets are indicated with parentheses or brackets. The solutions to. x\ge 4 x ≥ 4. are represented as. \left [4,\infty \right) [4,∞) .
