Question

Write each set in the indicated form.

If you need to use "..." to indicate a pattern, make sure to list at least four elements of the set.

Answer 1

Answer: (a)
`\{1,2,3,4\}` (b)
`\{x|x\text{ is an integer and }x\geq-6\}`

Explanation:

(a) Since the set consists of integers between 1 and 4 inclusive, so the set in roster form is:
`\{1,2,3,4\}`

(b) Since the set consists of integers greater than or equal to -6, so the set in the set-builder form is:
`\{x|x\text{ is an integer and }x\geq-6\}`
