Question

What is the range of the function f(x) = 3x - 12 for the domain (-2, 2)?

A. (3,12)
B. 4-6, -18)
c. (6, 18)
D. (12,3)

Answer 1

When x=-2

f(x) =3(-2) -12 =-6-12=-18

When x=2

f(x) = 3(2)-12=6-12=-6

So For the domain (-2,2)

Range of the function f(x) is (-18,-6)

So (-18 ,-6). is your answer.

Hope it helps....
