Question

write roaster form of A={x:x3=x,x belongs to R}

Answer 1

Given: The set A = { x : x³ = x , x belongs to R}

To find: The set in roaster form.

Solution:

• Now we have given the set in set builder form as:

                 A ={ x : x³ = x , x belongs to R}

• The condition is x³ = x.

• Putting x = 1, we get;

                 1³ = 1

                 True for x = 1

                 Putting x = -1, we get;

                 (-1)³ = -1

                 -1 = -1

                 True for x = -1

                 Putting x = 0, we get;

                 0³ = 0

                 0 = 0

                 True for x = 0

So the elements are: (1,1) , (-1,-1) and (0,0).

Answer:

          So the set in roaster form is A = { (1,1) , (-1,-1) ,  (0,0) }
