Write a rule for the linear function in the table. x f(x) 1 3 2 2 3 1 4 0 question 11 options: f(x) = x + 4 f(x) = 4x f(x) = x – 4 f(x) = 4 – x

We have
four cases
case 1-------------> f(x) = x + 4
case 2-------------> f(x) = 4x
case 3------------->f(x) = x – 4 
case 4------------->f(x) = 4 – x

I proceed to make a table in excel and assign different values ​​of x
see the attached table 

the answer is 
the case 4--------> f(x) = 4 – x------------ > this is the rule for the linear function in the table
 

As you know john locke said he wanted life liberty and the pursuit of happiness so thomas jefferson was inspired about what john locke said so thomas jefferson wrote the declaration of independence for people to be free for people to be happy
