The graph of the function f(x) = -(x+3)(x-1) is shown
1 answer:
The true statement about this function is that: B. the function is negative for all real values of x, where x < -3 and where x > 1.
<h3>What is a function?</h3>A function is a mathematical expression which can be used to define and indicate the relationship existing between two or more variables in a data set.
By critically observing the graph which models the given function (see attachment), we can logically deduce that the true statement about this function is that it's negative for all real values of x, where x is less than -3 and where x is greater than 1.

Answer:
The answer is below
Step-by-step explanation:
a) Given that the number of sample (n) = 300, therefore since n > 30, the distribution of the sample means is going to be normally distributed.
b) The mean of the distribution of sample means (also known as the Expected value of M) is equal to the population mean μ.
c) The standard deviation of the distribution of sample means is called the Standard Error of M, it is given by:
Simple, plug n chug...
t=2
u=-8
v=-0.5
Now, plug in what you have,
Now,
2-16=-14
Thus, your answer, -14.
t=2
u=-8
v=-0.5
Now, plug in what you have,
Now,
2-16=-14
Thus, your answer, -14.
