(a) Show that there is a one to one and onto function from the
interval (a, b) to the interval (c, d).
(b) Show that there is a one to one and onto function from the
interval (a, b] to the interval (c, d].
(c) Show that there is a one to one and onto function from the
interval (a, b) to R.

Wood and glass are used to make furniture. The share of wood in
the furniture price is 40%, while the share of glass - 10%. The
duty rate on wood is 20%, and on glass 10%. At the same time, the
finished furniture market is also protected: the duty on furniture
is 39%. We can say that as a result of the application of such a
commercial policy, the value added generated in the furniture
production sector increases by:
(a)...
Thus, A + (B + C) = (A + B) + C.
If D is a...
Thus, A + (B + C) = (A + B) + C.
If D is a set, then the power set of D is the set PD of all the
subsets of D. That is,
PD = {A: A ⊆ D}
The operation + is to be regarded as an operation on PD.
1 Prove that there is an identity element with respect to the
operation +, which is _________.
2 Prove every subset A of D has an inverse...
