A closed interval [a, b] represents the set of all real numbers x such that a ≤ x ≤ b. Example: [ 2, 7] is a closed interval which includes 2, 7 and all the real numbers between 2 and 7. We can write it with the help of compound inequality 2 ≤ x ≤ 7. In the set notation, we can express the open interval [ 2, 7] as { x | 2 ≤ x ≤ 7 }. Algebra. Convert to Interval Notation x<-3. x < −3 x < - 3. Convert the inequality to interval notation.

This video explains how to express an inequality as a graph and using interval notation.http://mathispower4u.comSometimes it helps to draw the graph first before writing the solution using interval notation. Remember to apply the properties of inequality when you are solving compound inequalities. The next example involves dividing by a negative to isolate a variable. Example. Solve for y. [latex]2y+7\lt13\text{ or }−3y–2\lt10[/latex]Multiply or divide both sides by the same positive number just as you would in an equation. If 2x + 5 < 7, first you would subtract five from each side to get 2x < 2. Then divide both sides by 2 to get x < 1. Switch the inequality if you multiply or divide by a negative number.
