What can be said about the inequality I6x + 2I > -16?
__ It is always true
__ It is never true
__ It is sometimes true
Please explain
Solution
It is always true because anything coming out of modulas is always positive.
If we put x as negative , it will also become positive.
If we put x=0 , it will become 2.
Therefore minimum value is 2 and all other values will be greater than 2.
So this inequality is always true
