Question

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}

E ∪ F is {2, 4, 6, 8}


True

False

Answer 1

What number(s) belong to set E? What number(s) belong to set F?
The symbol between E and F represents the union. This set contains all of the numbers that are in E OR F.

As an example,
\[A = \left\{ 1, 2, 3 \right\}\]
\[B = \left\{ 4, 5, 6 \right\}\]
\[A \cup B = \left\{ 1, 2, 3, 4, 5, 6 \right\}\]
