- Find mappings f,g and h of a set A into itself such that fg=hg and fh. Find mappings f,g and h of a set A into itself such that fg=fh and gh.arrow_forwardProve that if f is a permutation on A, then (f1)1=f.arrow_forwardLet X ={a,b,c} and let P(X) be the collection of all subsets of X. (3.1) List all the elements in P(X). (3.2) Define f : P(X) → Z by f(A) = |A|, where A ∈ P(X) and |A| is the number of elements in A. (3.2.1) Draw a picture of the function f. (3.2.2) Is f one-to-one. Explain. (3.2.3) Is f onto? Explain.arrow_forward
- 1 Let B be the set of all bounded sequences of real numbers and define the function d : B x B → R by d(x, y) = sup |an – Yn|- Show that (B, d) is a metric space.arrow_forwardProve that P(XnY) = P(X) ~P(Y) for all sets X and Y.arrow_forwardm* (A) = m (E). For any set A there exists a measurable set E containing A such thatarrow_forward
