Question

D= [xlx is a whole number}

E = {xlx is a perfect square between 1 and 9)
F = (xlx is an even number greater than or equal to 2 and less than 9]
Which of the following is D n F?
O (4, 6).
O (2, 4, 6)
O (2,4,6,8)
O (2)

Answer 1

Answer: C:
`D\cap F = \{2, 4, 6, 8\}`

Explanation:

Let's first find the specific numbers that are in sets D and F.

`D=\{0,1,2,\ldots\}`, as D has all whole numbers.

`F=\{2,4,6,8\}`, as all of these numbers are even, greater than or equal to two, and less than nine.

Since all the numbers in F are whole numbers, all of them would be in D. Hence, the intersection of both would just be {2, 4, 6, 8}.

`D\cap F = \{2, 4, 6, 8\}`
