Answer:
B
Explanation:
Inequalities of the type | x | ≤ a, have solution of the form
- a ≤ x ≤ a , so
| x | ≤ 4
- 4 ≤ x ≤ 4
The values of x are between - 4 and + 4, but can equal - 4 and 4 since the symbol is ' less than or equal to '
This is indicated on a number line by solid circles, where not equal to are denoted by open circles.
Thus the solution is Graph B
