Answer 1

C

Step-by-step explanation:

Answer 2

Answer: Choice C

`x < -2 \ \text{ or } \ x \ge 4`

========================================================

Step-by-step explanation:

The blue portion on the left is represented by
`x < -2` as it describes values smaller than -2. Notice the open hole at -2 which indicates we do not include this value. So that's why we go with
`x < -2` instead of
`x \le -2`

The blue portion on the right is represented as
`x \ge 4` describing values that are equal to 4, or larger than 4.

So overall, the entire graph visually represents x values such that
`x < -2 \ \text{ or } \ x \ge 4`

Side note: the "or" means we pick one region or the other, but not both regions at the same time.
