Very confused.

2. I think I have the answer. It utilises absolute values.... Is this a rule breaker? I don't think so...
N = [ x . abs (3^(abs(x)) ] / [abs (x)]

If you enter values of x, from negatives through zero to positives, you get that sequence...
x = (-3, -2, -1, 0, 1, 2, 3) --> n = (-27, -9, -3, 0, 3, 9, 27)

(Not my work - DH)

3. Can't divide by 0 so absolute doesn't work

It is a standard deviation curve. If you plot it into a graphics calc you can see the next intercept of the lines. There is no trick to it.

Here is the answer for those interested.

8. This answer is straight from the mathematician lecturer at DHs Uni.
Apparently v is the "or" operator in logic
