Answer:
Recursive
a(1) = 9 ; a(n+1) = 3 * a(n)
Explicit
a(n) = 9 * 3^(n-1)
Since the whole set is composed of a total of 55 people, with 45 people being drinks of either coffer or tea, then the remaining people not included in the 45 would be the non-drinkers. So 55-45, meaning there are 10 people who drink neither tea nor coffee. To obtain the probability:
10/55 = 2/11 = 0.182
Therefore, the probability of a person being picked at random does not drink either coffee or tea is 0.182.

1 ) f ( x ) = 3 x
He can write { 9, 12, 18, 21, 27 } comic strips.
2 ) f ( x ) = 5 x - 3
- 13 = 5 x - 3
5 x = - 10
x = -2, etc.
The domain is: { - 2 , - 1 , 0, 3, 4 }
3 ) f ( x ) = 2 x
It will take { 8, 20, 28, 32, 36 } hours.
