Answer:
C
Step-by-step explanation:
0 = 8 is a false statement which means the system has no solutions
The answer is 1 Bcuz u have to first plug in -4 for f then solve the equation by adding like terms and dividing
Answer:
a) Suppose that F is ordered in ascending order: 
. Then, the complement of F can be written as
which is the union of a finite number of open intervals, then 
is an open set. Thus, F is a closed subset of the real numbers.
b) Take an arbitrary element of F, let us say 
. Now, choose a real number 
such that
there are not other element of F, because is less that the minimum distance between and its neighbors.
In case that 
we only consider 
, and if 
we only consider 
.
Then, all points of F are isolated.
