Answer:
see the attachment
Step-by-step explanation:
(a) S1 is the set of all subsets of {t, u, v}. There are 2^3 = 8 subsets, the EMPTY set being one of them. They are listed in the attachment.
It seems likely your answer will need to match that shown in the attachment:
{EMPTY, {t}, {u}, ... , {t, u, v}}
where the elements of multi-element sets are listed separately: {t, u}, not {tu}.
__
(b) S2 is the set S1 with <em>w</em> added to each subset. (see the attachment for a listing)
__
(c) Correct, the sets are disjoint, since every set in S1 is different from every set in S2.
__
(d) Each set has 8 elements; the sets are the same size. You know this because you created set S2 from set S1. (See (b), above.)
__
(e) The sets are disjoint (see (c)), so the total number of elements in their union is the total of the numbers of elements in each set: 8 + 8 = 16.
__
(f) P(A) is undefined here, so none of these questions can be answered.
Check the picture below.
notice, when dividing we have to put the dividend in descending order, now, the cubic, square and single terms are there, but they have a coefficient of 0, as you see in the picture in green, so we add those properly.

Answer:
a) no
b) yes
Step-by-step explanation:
a) You cannot draw the graph around x=0 without lifting your pencil. The function is not continuous at x=0.
__
b) You can draw the graph around x=1 without lifting your pencil. The function is continuous at x=1.
_____
<em>Additional comment</em>
In technical terms, the limit from the left at x=0 is 2; the limit from the right is 3. These are different, so the function is not continuous there.
On the other hand, the left and right limits at x=1 are the same (both 2), and are equal to the value of the function at that point (f(1)=2). Hence, the function is continuous at x=1.
