The composite function 
works like this:
- Take a number
as input - Evaluate h(x) = 3x. Let's call this output z.
- Evaluate g(x) = 1/(z+2)
So, if we substitute back z = 3x, the final output is 1/(3x+2). We know that the denominator of a fraction can't be zero, so we must impose

Step-by-step explanation:
Answer:
Mean : ≈ 12.7
Median: ≈ 13.5
Step-by-step explanation:
To find the mean you must add all the numbers and divide by the # of numbers in the set.
8+12+13+14+14+15 = 76
76/6 ≈ 12.7
To find the median you have to order the numbers from least to greatest, the middle number should be the median, but in this case two numbers are in the middle.
8, 12, 13, 14, 14, 15
So you have to add 14 and 13, which is 27.
Then divide by 2 which is ≈ 13.5
