Given the piecewise function:
Let's select the graph which represents the function.
We have the graph below:
For f(x) = 3, the graph will be a horizontal line on y = 3 which has an open dot on x = 0 and a closed dot on x = -2
For f(x) = 1 if x = 0, the graph will have a closed dot located on the point (0, 1)
For f(x) = -(x + 1) if 0 < x ≤2, the graph will have a negative slope with an open dot on (0, -1) and closed dot on (2, -3)

Graph B
Answer:
The sample size is
Step-by-step explanation:
From the question we are told that
The sample standard deviation is
The mean difference of the two groups is
The standard error is
=>
Let assume that the confidence level is 95% hence the level of significance is
=>
So the critical value of obtained from the normal distribution table is
Generally the margin of error is mathematically evaluated as
Generally the sample size is mathematically represented as
=>
=>
