f(x) = x+4 is the first function
We plug in -4 for x in f(x) = x+4
f(-4) = -4 + 4 = 0
So the graph starts at (-4,0)
Now plug in 3 for x in f(x) = x+4
f(3) = 3 + 4 = 7
So the first function ends at (3,7)
Second function is f(x) = 2x - 1
We plug in 3 for x in f(x) = 2x-1
f(3) =2(3)-1 = 5
So the second graph starts at (3,5)
We plug in 6 for x in f(x) = 2x-1
f(6) =2(6)-1 = 11
So the second graph ends at (6,11)
3<=x<6 so 6 is excluded from x
The range of the following piece wise function is 0 to 11
answer is [0,11)

Answer:
Step-by-step explanation:
Given that in our industry on average a firm paid out record year end bonuses of $125,500 per employee for 2008. We would like to take a sample of employees at our firm to see whether the mean year end bonus is different from the reported mean of $125,500 for the population.
1. Sample Mean =
118000
2. Population Mean = 125500
3. Population Standard Deviation = 30000
4. Sample size = 40
5. Alpha Error = 5%
6. Confidence Coefficient = 95%
7. Calculate Test Statistic = Mean difference /s td error = -1.581
8. Rejection Region Critical Value = If Z statistic is below -1.96 or above 1.96
