Answer: Option B
Step-by-step explanation:
By definition, only those functions that are one to one have an inverse function.
A function is one by one if there are not two different input values,
and
, that have the same output value y
Note that the function
is not a one-to-one function
When x=2 
When x=8 
Note that the function
is not a one-to-one function
When x=1 
When x=-1 
Note that the function
is not a one-to-one function
When x=1 
When x=-1 
Then the answer is the option B.
You can verify that The function
is a one-to-one function and therefore its inverse is a function
Answer:

Step-by-step explanation:
Given that a club can select one member to attend a conference. All of the club officers want to attend. There are a total of four officers, and their designated positions within the club are President (P), Vice dash President (Upper V )comma Secretary (Upper S )comma nbspand Treasurer (Upper T ).
Sample space would be
a){ {P}, {V}, {S} {T}} is the sample space with notations standing for as given in the question
b) Each sample is equally likely. Hence we have equal chances for selecting any one out of the four.
If probability of selecting a particular sample of size I is p, the by total probability axiom we have
\begin{gathered}4p =1\\p =0.25\end{gathered}
4p=1
