Consider the inequality : $| x | < 20$ The solution of this inequality consists of one or more of the intervals $(-\infty, A)$, $(A,B)$ and $(B,\infty)$ where $A < B$.

Find $A$

Find $B$

For each interval, answer YES or NO to whether the interval is included in the solution.

$(-\infty, A)$

$(A,B)$

$(B,\infty)$
