Where the inequality is true, y-values on the graph will be a 1.
If you look at the table, 0's will be listed where the inequality is
false and 1's will be listed where the inequality is true.
Determine exact cut off points by using the intersection option.
Remember that the calculator cannot draw an open or closed circle
on the intervals. You will have to determine which circle is
needed based upon whether the inequality includes "equal to".
Find the endpoints by using the intersect option (2nd TRACE #5
If you turn off the axes (FORMAT - 2nd ZOOM),
you will be able to see the graphing of the 0's and 1's more clearly.
Notice that the small vertical segment connecting the 0's to the 1's
is simply the calculator being set in "connected" mode.
Change to "dot" mode to remove this segment.
