Question

Re-write the set W by listing its elements. Use the appropriate set notation.

Answer 1

For this, we will use roster notation.

We know that x has to be an integer, which is any number not a fraction. We also know that x is greater than 3, but not equal to it, therefore 3 will not be included. Our set will start with 4.

Since there are many, many integers greater than 3, we only have to list the first 5 and then add "..." to show the pattern continues.

W = {4, 5, 6, 7, 8, ...}
