Step-by-step explanation:

The question is incomplete as g(x) is not properly written.

I'll assume the following:

Required

Determine (f o g)(-6)

In functions:

(f o g)x = f(g(x))

So:

First, we calculate g(-6)

Substitute 13 for g(-6) in

Next, we calculate f(13)

Hence:

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
