You have already had your three strikes. I cannot believe that 3 different tutors have given me three different solutions. If the tutors do not come up with a common answer this round, I shall have no other choice but cancel my subscription.

The domain and range of the function n(x) are [-6,9] and [-8,10], respectively. Additionally, n is increasing on the intervals [-6,1] and [5,9) and decreasing on the interval [1,5].

Let q(x) = 4 - 2n(5-x)

a) Find the domain and the range of q(x).

b) On what intervals is q increasing and decreasing?
