SOAL PA NOMOR 5

5a. Show that if f maps X into Y and A is a subset of X, B is a subset of  Y then

f(f^(-1)(B)) is a subset of B

NB : f^(-1) is the inverse image ( peta invers).

5b. Show that if  f  maps X onto Y and B is a subset of Y, then 

f(f^(-1)(B)) = B

NB :  f  maps X onto Y = f onto/surjective ( pada)

SOAL PA NOMOR 4

4a. Prove that every integer is either even or odd, but never both.

4b. Prove that if b > 0 then b|a if and only if a mod b = 0.
