Question 145922
The graph of the interval (-4,10) is simply the shaded region from -4 to 10 on the number line. Notice how parenthesis are used, so this means that we must use <b>open</b> circles at the endpoints




So here's what the graph looks like:


{{{drawing(500,80,-5, 12,-10, 10,
number_line( 500, -5, 12),

circle(10,0,0.3),
circle(10,0,0.3),
circle(10,0,0.3),
circle(10,0,0.3-0.02),

line(-4,0,10,0),
line(-4,0.30,10,0.30),
line(-4,0.15,10,0.15),
line(-4,-0.15,10,-0.15),
line(-4,-0.30,10,-0.30),

circle(-4,0,0.3),
circle(-4,0,0.3),
circle(-4,0,0.3),
circle(-4,0,0.3-0.02)
)}}}



note: the <b>open</b> circles at -4 and 10 tell us to exclude -4 and 10 from the  solution set.
