STEP - BY - STEP EXPLANATION
What to do?
Fill in the blank space.
Given:
Elements common to both (-∞, 2) and (-∞, 4) are also known as the intersection of the two sets.
Observe that all integers from -∞ to 2 are both common in the two sets. However, 3 and 4 are not common as they are elements contained only in the second set and not in the first set.
ANSWER
The set of common element to both ( -∞ , 2) and ( -∞ , 4) is ( -∞ , 2)
This represents intersection of these intervals.
