In the Figure below is shown the graph of this function. We have the following function:

The
occurs when
, so:

Therefore, the
is the given by the point:

From the figure we have three
:

So, the
occur when
. Thus, proving this:

This answer is going to be X=-5 because you are solving for X in the parentheses.
A,d,b, and then c ,basically least to greatest
Answer:

Step-by-step explanation:
Given

Required
The standard deviation
First, calculate the expected value E(x)

So, we have:


Next, calculate E(x^2)

So, we have:


The standard deviation is:
