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.
. 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.
 increases by 1.



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


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