Given the input in the table which function rule produces the output?

b)

Step-by-step explanation:

The given table :-

Input           4               5                7                8

Output        18              22              30              34

Let's check all the options

a)

At x= 4,

At x= 5 ,  , thus it not the correct function.

b)

At x= 4 ,  

At x= 5 ,  

At x= 7 ,  

At x= 8 ,   , thus it is the function rule that  produces the output.

c)

At x= 4 ,  

At x= 5 ,    , thus it not the correct function.

d)  

At x= 4 ,  

At x= 5 ,    , thus it not the correct function.

Hence, the correct function rule that produces the output = b)

do you mean add both of the equations together

because if you do the answer is 10x-5
