Divide by 2 both sides. X 2n where n N. So the domain in set builder notation is x 3 x 4.
Set-Builder Notation looks like this.
A square bracket denotes inclusion in the set while a parenthesis denotes exclusion from the set. X 2n 1 where n N. If you already have a set of real numbers R then the subset of positive integers could be written as follows. We can use set-builder notation.
