Quizplus · Accepted Answer

The union of the intervals $(7, \infty)$ and $[10, \infty)$ covers all values greater than 7, including 10 and beyond, which is exactly represented by the interval $(7, \infty)$.

Find Intersections and Unions of Intervals Use Graphs to Find (7,∞)∪[10,∞)( 7 , \infty ) \cup [ 10 , \infty )(7,∞)∪[10,∞)
