Given the domain what is the range

the Range is = { -9, 3, 9}

which agrees with the answer shown as option A in the list

Step-by-step explanation:

Given the relationship :

3 x + y = 3

we can find the Range that corresponds to the Domain: {-2, 2, 4} by replacing one by one these numbers of the domain in the "x" value in the equation, and finding what y results into:

(a)  3 (-2) +y = 3

-6+ y = 3

y = 3 + 6 = 9

(b)  3 (2) + y = 3

   6 + y = 3

y = -3

(c) 3 (4) + y = 3

   12+ y = 3

    y = -9

Therefore, the Range is = { -9, 3, 9}
