Answer 1

Answer:

answer is:

Step-by-step explanation:

x € [-2,-1,0,1,2]

this is roaster form

Answer 2

Answer:

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

Note:

★ Set : A well defined collection of distinct objects is called set .

★ There are two ways of write a set .

1) Set builder form

2) Roster form

★ Set builder form : The common properties of the elements are written .

★ Roster form : The elements are already listed .

Solution:

Here,

The given interval is ;

x € [-2 , 2] , x € Z .

Now,

Let the required set be X , then ;

The given interval set in roster form will be given as ;

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

Also,

The given interval set in set builder form will be given as ;

X = { x : x € Z , -2 ≤ x ≤ 2 }
