Step-by-step explanation:
The given statement is true.
Step-by-step explanation:
Given sets are:
D = {x|x is a whole number}
E = {x|x is a perfect square between 1 and 9}
F = {x|x is an even number greater than or equal to 2 and less than 9}
as the sets are given in set builder notation,, we will first write the sets in set notation.
So,
D = {0,1,2,3,4,...}
E = {4,9}
F = {2,4,6,8}
Now,
EUF = {4,9} U {2,4,6,8}
= {2,4,6,8}
Hence,
The given statement is true.
