Question

Identify the correct union of intervals for the inequality. $x \leq - 18$ or $x > 4$
A) $\quad ( - \infty , - 18 ] \cup ( 4 , \infty )$
B) $\quad ( - \infty , - 18 ) \cup ( 4 , \infty )$
C) $\quad ( - \infty , - 18 ] \cup ( 4 , \infty ]$
D) $\quad ( - \infty , - 18 ] \cup [ 4 , \infty )$
E) $( - \infty , - 18 ) \cup [ 4 , \infty )$

Quizplus · Accepted Answer

The inequality $x \leq - 18$ includes -18 and extends to negative infinity, represented as $(- \infty, -18]$. The inequality $x > 4$ starts just after 4 and extends to positive infinity, represented as $(4, \infty)$. The union of these two intervals is $(- \infty, -18] \cup (4, \infty)$.
