Find Intersections and Unions of Intervals
Use graphs to find the set.
-$( - \infty , 9 ) \cap [ - 2,12 )$
A) $[ - 2,9 )$
B) $( - \infty , 12 )$
C) $( 9,12 )$
D) $( - \infty , - 2 ]$

Question

The intersection of the two intervals includes all numbers from -∞ to 9 that are also in the interval from -2 to 12 (excluding 12). This can be shown graphically by shading the overlapping region, which gives the interval [ - 2,9 ).

Find Intersections and Unions of Intervals Use Graphs to Find (−∞,9)∩[−2,12)( - \infty , 9 ) \cap [ - 2,12 )(−∞,9)∩[−2,12)
