Question

{x: x is an integer, x2 ≤ 16}​ roster form

Answer 1

Answer:

{1,2,3}

{1, 2, 3, -1, -2, -3}

Step-by-step explanation:

A= {x :x is a natural number, x² < 16}

x = 1, 2, 3

A = {1, 2, 3]

B = {x: x is an integer; [xl <4}

x = 1, 2, 3,-1, -2, -3 B = {1, 2, 3, -1, -2, -3}

AUB = {1, 2, 3, -1, -2, -3)
