Answer:

A = { -3, -2, -1, 0, 1, 2, 3 }


Step by Step Explanation:


We can represent the sets in the three forms.

They are :

1) Descriptive form. It can be expressed in words.

Eg. A is a set of integers from -4 to 4

2) Set Builder form: It is the representation of elements by using symbols.

Eg. A = { x | x > -4 and x < 4 }

3) Roster form. It is the representation of elements directly. It is easy to understand.

Eg. { -3, -2, -1, 0, 1, 2, 3 }

Points to Remember:

1) Be careful that you should not repeat the element.

2) greater than or lesser than some number means, neglect that number and include between that numbers.

3) If they give starting element and not gave ending element, better put three consecutive dots ( ellipsis ) which denotes infinite set.

4) If greater than or equal to and less than or equal to some number means, write the number too.
