# List all the elements of the following sets:

C = {x : x is an integer, x^{2} ≤ 4}

Answer :

Integers are ……-4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8

x^{2} = 4

x= 2

so

(0)^{2}= 0

(1)^{2} = 1

(2)^{2}= 4

(-2)^{2} = 4

(-1)^{2} =1

The elements of the set are -2, -1, 0, 1, 2

C= {-2, -1, 0, 1, 2}
