Answer 2

Answer:

The set is {0}.

Step-by-step explanation:

• Any set can be expressed symbollically in two ways,that is,by identifying the properties of its element or,explicitly mentioning its elements.The second method is called writing in its roster form.
• To write the roster form,one only need to find out each element explictly.
• Here,to identify the element we only have to solve for x in x+1=1 such that x is in integer.
• Solving we get,x=0 which is in deed an integer.
• Thus the roster form is {0}.
