Question 146195
*[Tex \LARGE 6<x<18] in interval notation is:   <font size="8">(</font>*[Tex \LARGE \bf{6,18}]<font size="8">)</font>





Here's the graph of *[Tex \LARGE 6<x<18] 



{{{drawing(500,80,1, 23,-10, 10,
number_line( 500, 1, 23 ),

blue(line(6,0,18,0)),
blue(line(6,0.30,18,0.30)),
blue(line(6,0.15,18,0.15)),
blue(line(6,-0.15,18,-0.15)),
blue(line(6,-0.30,18,-0.30)),




circle(6,0,0.25),
circle(6,0,0.20),




circle(18,0,0.25),
circle(18,0,0.20)




)}}} 



Note:

There is an <b>open</b> circle at {{{x=6}}} which means that we're excluding this value from the solution set

Also, there is an <b>open</b> circle at {{{x=18}}} which means that we're excluding this value from the solution set.
