Question

all the subsets of
C = {x} ?​

Answer 1

Answer:

              { }  and  {x}

Step-by-step explanation:

∅ = { } ⊂ C     That is, the empty set is a subset of C.  Actually, the empty set is a subset of every set!

C = {x} ⊂ C     That is, C is a subset of C.  Every set is a subset of itself.

As there is only one element in C, these two are the only subsets.
