Question

Express in set builder notation the set of numbers that is indicated on the number line

Answer 1

The numbers indicated on the number line are:

`-3,-2,-1,0,1,2,3,4`

The given numbers are all integers.

Therefore, the set of the given numbers expressed in set builder notation is as follows:

`\lbrace x|-3\leq x\leq4\text{ and }x\in\text{ Integers}\rbrace`

-3 ≤ x ≤ 4 and x ∈ Integers
