**Steve**, Thursday, March 7, 2013 at 3:35pmIf 2 <= x < 6

draw the number line

place a dot at 2 and an open circle at 6

shade the line between the dot and the circle.

**Dr. Jane**, Thursday, March 7, 2013 at 3:36pmfor the 2 you would color in a circle at 2 because it is less than or equal.

for the 6 you would put an open circle (not colored in)

Connect the two points with a dark line. That is your solution.

To check that you are correct... choose a value for x in that region and check it in the original inequality.

In some courses, they don't use the colored and no-colored circle.

they use ( ) or [ ]

The ) is used for the open circle

the ] is used for the colored in circle.
