[ 1/1Inequality]
Assignment:Find the solution set of inequality -2 ≤x+1 <1 .
Question type: Inequality
Solution:
The inequality can be reduced to 2 inequalities：
-2 ≤ x + 1 (1)
x + 1 <1 (2)
From inequality(1)：
x ≥ -3
From inequality(2)：
x < 0
From inequalities (1) and (2)
-3 ≤ x < 0 (3)
The final solution set is :
-3 ≤ x < 0
