Write a function rule based on the table below. x f(x) 0 -4 2 2 4 8 a. f(x) = 6x-4 b. f(x) = 3x-4 c. f(x) = -6x+4 d. f(x) = -4x

To find a function that represents these values, just substitute x-values in and look for a function that gives you the correct f(x).

A) This works for 0, but not 2
B) This works for 0, 2, and 4 making it the right answer.

Step 1: 6x-10=1; step 2: 6x=11
