WebWith interval notation, we use use round parentheses, ( or ). With inequalities, we use "less than or equal to": ≤ or "greater than or equal to": ≥ to include the endpoint of the interval. With interval notation, we use use square brackets, [ or ]. To combine two intervals, use U (an uppercase letter u) for union: ∪ ∪.

WebThe parentheses tell you that the inequalities do not include the end values of -2 and 5. If the inequality is: -2≤x≤5, then the interval notation is: [-2, 5] The square brackets tells you that the end values are included in the interval. If you have an inequality like: -2≤x<5, then the interval notation is: [-2, 5) WebMar 7, 2024 · Graph the solution to y < 2x + 3. The first step is to find the "equals" part. For two-variable linear inequalities, the "equals" part is the line. y = 2 x + 3. Now we are ready to do the "y less than" part. In other …
