I need help finding the answer

A

Step-by-step explanation:

Substitute each of the values of x from the domain into f(x), that is

f(- 12) = × - 12 + 2 = - 20 + 2 = - 18 ⇒ (- 12, - 18 )

f(- 3) = × - 3 + 2 = - 5 + 2 = - 3 ⇒ (- 3, - 3 )

f(0) = × 0 + 2 = 0 + 2 = 2 ⇒ (0, 2 )

f(3) = × 3 + 2 = 5 + 2 = 7 ⇒ (3, 7 )

f(12) = × 12 + 2 = 20 + 2 = 22 ⇒ (12, 22 )

The set of ordered pairs is set A
