Question 201184
Simply draw a line segment in which has the left endpoint (x=0) as an open circle and the right endpoint (x=3) as a closed circle.


{{{drawing(500,80,-5, 8,-10, 10,
number_line( 500, -5, 8 ,3),

blue(line(0,0,3,0)),
blue(line(0,0.30,3,0.30)),
blue(line(0,0.15,3,0.15)),
blue(line(0,-0.15,3,-0.15)),
blue(line(0,-0.30,3,-0.30)),
circle(0,0,0.25),circle(0,0,0.20)

)}}} Graph of the solution set


Note:

There is an <b>open</b> circle at {{{x=0}}} which means that we're excluding this value from the solution set

Also, there is a <b>closed</b> circle at {{{x=3}}} which means that we're including this value in the solution set.
