Write a function rule for the table. n: 1, 2, 3, 4. f(n): 3,2,1,0

Question

A- f(n)= 4-n^

B- f(n)= n^4

C- f(n)= 3n

D- f(n)= n^2

  is it A

PLEASE HELP ME! 

THANK YOU!

Answer 1

The f(n) values have a common difference.  This means that there is a common slope between the values.  The same occurs for n values too.  When you have a slope, it indicates that the relation between n and f(n) is linear.  Based on this pattern, n=0 will give an f(n) value of 4.  This is the y-intercept (0, 4).  Therefore, you chose the correct answer choice.

 

f(n) = 4 - n

 

But I am not sure why you have a carrot symbol in your answer choice though.
