D) $( - \infty , \infty )$

Question

Quizplus · Accepted Answer

The set $( 7 , \infty ) \cup [ 13 , \infty )$ includes all numbers greater than 7, which means it starts just after 7 and extends to infinity, making option A correct. The union with $[ 13 , \infty )$ doesn't change the set because all numbers from 13 to infinity are already included in $( 7 , \infty )$.
