    Interpretation of question: Find the range, given the f (x) = 3x - 12 and the domain is from (-2,2).

    Since the function is linear, it will always be increasing from left to right.

    We can get the lower and upper bounds of our function's range by plugging in the lower and upper bounds of the domain into the function.

    1) Plug - 2 into the function.

    3 (-2) - 12 = - 18

    2) Plug 2 into the function.

    3 (2) - 12 = - 6

    The range is (-18, - 6).
