AT SOMA
Select test values in each interval and
substitute those values into the
inequality.
Note:
If the test value makes the inequality
true, then the entire interval is a
solution to the inequality.
If the test value makes the inequality
false, then the entire interval is not a
solution to the inequality.
Use interval notation or set notation to
write the final answer.
