Document Summary
,b but not including a: closed interval: consists of all numbers between a and. , ba: you can mimic these denotations on a number line as well. Simple include a [ ] or ( ) as the endpoints on the number line, and you will have properly described the interval of the inequality. Split points: basically, if we have a more complex inequality, sometimes they will have a spot where the factor is 0. + 2 < 0 x ( 3. Has two spots (3 and -2) where the inequality will equal 0. This means we have to use certain test points in between the 0 spots to determine if the solution set still works. First, factor the side of the equation and determine the 0 points. Then, make a number line and plot each 0 point. 0 point and see if it fits the rule for the inequality.
