Answer 3

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}

Answer 4

True or false?

it is true

Answer 6

false because 2,6,and 8 are not squares

Answer 7

we have:
\[\begin{gathered}
F = \left\{ {2,4,6,8} \right\} \hfill \\
E = \left\{ 4 \right\} \hfill \\
\end{gathered} \]
so:
\[E \cup F = F = \left\{ {2,4,6,8} \right\}\]
