**Steve**, Tuesday, July 9, 2013 at 10:59amCan't tell. If f(x) is linear, then just multiply the range by -2 to get [-18,24]

For example, if f(x) = 7/5 x - 11/5

then -f(2x) = 22/5 - 14/5 x

and the range is indeed [-18,24]

But, if f(x) is not linear, say

f(x) = 7/5 x^2 - 403/5 then

-f(2x) = 806/5 - 28/5 x^2

and the range is now [-986/5,-566/5]
