dalvyx [7]

Answer:

(x)= 2, 5, 8, 11

Use the formula  

a n  =  a 1  +  d  ( n  −  1 )

to identify the arithmetic sequence.

a n  =  3 n  −  1

f(x)= 5, 11 17, 23

Use the formula  

a n  = a 1  +  d  ( n − 1 )

to identify the arithmetic sequence.

a n  =  6n  −  1

x      f(x)

Step-by-step explanation:

Write a rule for the linear function in the table.

x;     f(x)

2      8

5     17

5      11

11    23

A; f(x) = x + 5

B;f(x) = x + 1

C;f(x) = 2x + 1

D;f(x) = –2x – 1

If all your solutions are  

A; f(x) = x + 5

B;f(x) = x + 1

C;f(x) = 2x + 1

D;f(x) = –2x – 1

None of the above will work with the data set you have presented.
