Which of the following functions f (x) represent the order pairs:

{ (-2,-7), (-1,-4), (0,-1), (1,2), (2,5)

A. f (x) = 2x

B. f (x) = 3x-1

C. f (x) = -3x+5

D. f (x) = 3x+5

B. f (x) = 3x-1

Step-by-step explanation:

{ (-2,-7), (-1,-4), (0,-1), (1,2), (2,5) are solutions of f (x) = 3x-1

Plug in

(-2,-7) : f (x) = 3 (-2) - 1 = - 6 - 1 = - 7

(-1,-4) : f (x) = 3 (-1) - 1 = - 3 - 1 = - 4

(0,-1) : f (x) = 3 (0) - 1 = - 1

(1,2) : f (x) = 3 (1) - 1 = 3 - 1 = 2

(2,5) : f (x) = 3 (2) - 1 = 6 - 1 = 5
