Question 154212
Do you want to graph this?


Simply plot two open circles at x=-3 and x=0. Now starting at x=-3, shade to the left towards negative infinity on the number line. Now move onto x=0 and shade to the right towards positive infinity like this:


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


circle(-3,0,0.25),
circle(-3,0,0.20),


blue(arrow(-3,0,-8,0)),
blue(arrow(-3,0.30,-8,0.30)),
blue(arrow(-3,0.15,-8,0.15)),
blue(arrow(-3,-0.15,-8,-0.15)),
blue(arrow(-3,-0.30,-8,-0.30)),



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


blue(arrow(0,0,5,0)),
blue(arrow(0,0.30,5,0.30)),
blue(arrow(0,0.15,5,0.15)),
blue(arrow(0,-0.15,5,-0.15)),
blue(arrow(0,-0.30,5,-0.30))


)}}}



Note:

There is an <b>open</b> circle at {{{x=-3}}} which means that we're excluding that value from the solution set.



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