I don't know whether or not you meant to write 3(-x) - 2 or 3 - x - 2. for the first case do 3(-*-2) - 2 which is -6 -2 which is -8. for the second it is 3 - -2 -2 which is 3.

Answer:

f(-2) =7

Step-by-step explanation:

f(x) = 3^(-x) – 2.

Find f(-2)

Let x =-2

f(-2) = 3^(-x) -2

        3^ (+2)-2

        9-2

         7
