Question

If A = {x | x is an odd integer), B = {x | x is an even integer), C = {2,3,4,5), and D = {6, 7, 8, 9), list the element(s) of the following set An D= (Use a comma to separate elements in the set.)

Answer 1

Answer:

A ∩ D = {7, 9}

Explanation:

Given that:

A = {x | x is an odd integer}

Let A = {3, 5, 7, 9}

B = {x | x is an even integer}

Let B = {2, 4, 6, 8}

C = {2, 3, 4, 5}

D = {6, 7, 8, 9}

A ∩ D = {7, 9}

This is the intersection of A and D
