To solve
, isolate the absolute value, create two cases, and combine solutions. The correct answer is
, and the appropriate choice is D.
Let's solve the inequality step by step:
1. Isolate the Absolute Value:
2. Create Two Cases:
- Case one:
- Case two:
3. Combine the Solutions:
- Combine the solutions from both cases:
Now, let's look at the choices:
A.
or
- Incorrect
B.
and
- Incorrect
C.
or
- Incorrect
D.
and
- Correct (it marks the interval from -
to
)
So, the correct solution is
, and D marks the interval from -
to
, so D is the correct choice.
