Answer:
[tex]-2 \geq w \geq 2[/tex]
Step-by-step explanation:
Given
[tex]|-w| \geq 2[/tex]
Required
Solve for w
[tex]|-w| \geq 2[/tex]
In absolution functions;
[tex]|-w| = |w|[/tex]
So, the given expression can be rewritten as
[tex]|w| \geq 2[/tex]
Removing the absolute sign, will gibe
[tex]w \geq 2[/tex] or [tex]w \leq -2[/tex]
When the second inequality os rewritten, it gives
[tex]w \geq 2[/tex] or [tex]-2 \geq w[/tex]
Reorder both inequalities
[tex]-2 \geq w[/tex] or [tex]w \geq 2[/tex]
Lastly, both inequalities are combined
[tex]-2 \geq w \geq 2[/tex]
