<------------------->
    4        5         6
    o...................o              <----represents what you would shade in on the number line...notice the o or "holes" in the graph at 4 and 6 since the inequality indicates that 4 and 6 are not included but everything between them is included

interval notation is the same as the inequality except that you restrict within parenthesis or brackets. but since 4 and 6 are not included you use parenthesis
(4,6)
