Answer:
D. 
Step-by-step explanation:
We have been given a table of values. We are asked to write a function rule for our given table.
We can see from our given table that
. This means that the y-intercept of our given function is 3.
We can see that with each increase in x, the value of
increases by 1.



This means slope of our given function is 1.
Upon substituting
and
in slope intercept form of equation, we will get:


Therefore, our required function is
and option D is the correct choice.
