You'd know that 16 = 2^4, 8 = 2^3, 4 = 2^2, 2 = 2^1 and 1 = 2^0 so the base is 2, and

you need to figure out how to make -2 become 4, -1 become 3, 0 become 2, 1 become 1 and 2 become 0.

y = 2 ^ (2 - x)

The values for f(x) are decreasing as x increases so it's not growth.

That's some of it anyway, hope it helps.
