Answer:
-4 ≤ x ≤ 0
Step-by-step explanation:
Given
x ≤ 0 or x ≥ -4
Required
Write using Interval notation
x ≤ 0 or x ≥ -4
This can be rewritten as
x ≤ 0 or -4 ≤ x
Reorder the above inequality to give:
-4 ≤ x or x ≤ 0
The above inequality can then be combined to give
-4 ≤ x ≤ 0
Hence, the interval notation of x ≤ 0 or x ≥ -4 is -4 ≤ x ≤ 0
