The graph which represents the polynomial function g(x) is:
the 2nd graph in the second line
Step-by-step explanation:
g(x) = x³ + x² - 17x + 15 is a cubic function because the greatest power
of x is 3
All graphs represent cubic functions
So to find which graph which represents g(x) we will do these steps
1. Put x = 0 to find the y-intercept
2. If there are more than one graph have the same y-intercept we will
find the maximum and the minimum points of the cure
3. If you still don't know which graph find the x-intercepts
Now let us find the graph which represents g(x)
∵ g(x) = x³ + x² - 17x + 15
∵ x = 0
∴ g(0) = (0)³ + (0)² - 17(0) + 15
∴ g(0) = 15
∵ g(0) is the y-intercept
∴ The graph intersect the y-axis at point (0 , 15)
There is only one graph intersects y-axis at point (0 , 15)
The attached figure is the graph of g(x)
The graph which represents the polynomial function g(x) is:
the 2nd graph in the second line

Answer:
The margin of error is 6.45.
Step-by-step explanation:
The complete question is:
As an early intervention effort, a school psychologist wants to estimate the average score on the Stanford-Binet Intelligence Scale for all students with a specific type of learning disorder using a simple random sample of 36 students with the disorder.
Determine the margin of error, of a 99% confidence interval for the mean IQ score of all students with the disorder. Assume that the standard deviation IQ score among the population of all students with the disorder is the same as the standard deviation of IQ score for the general population, σ = 15 points.
The (1 - <em>α</em>)% confidence interval for population mean <em>μ</em> is:
The margin of error for this interval is:
Given:
<em>n</em> = 36
σ = 15
(1 - <em>α</em>)% = 99%
Compute the critical value of <em>z</em> for 99% confidence level as follows:
*Use a <em>z</em>-table.
Compute the value of MOE as follows:
Thus, the margin of error is 6.45.
