Discrete Mathematics and Its Applications | 7th Edition

List the members of these sets.

a) {x | x is a real number such that \(x^2=1\)}

b) {x | x is a positive integer less than 12}

c) {x | x is the square of an integer and x<100}

d) {x | x is an integer such that \(x^2=2\)}

**Accepted Solution**

Step 1 of 4

In the given problem we have to list the members of these sets.

a) {x | x is a real number such that }

Real number includes all types of numbers like rational , fractions , whole numbers etc.

For

This is only possible by {-1,1}

Put x = -1

Then

Similarly put = 1

Then

Therefore the set of x will be {-1,1}
