7 & 8 please!!!!!!!!!!!!!

                                                  Question # 7

Answer:

Yes. It displays exponential behavior.

To determine:

We have to determine whether the set of data shown above displays exponential behavior. Write Yes or No. Explain why or why not

Solution Steps:

Considering the set of data

x                    2                    5                    8                    11

y                  480                120                 30                  7.5

To determine whether the set of data shown above displays exponential behavior, we would first need to check the pattern of x and y values.

The set of data will be exponential if

  • there is a constant change in x
  • there is a constant ratio in y

From the data set, it is clear that there is a constant change in the values of x. For example,

  • 2 + 3 = 5
  • 5 + 3 = 8
  • 8 + 3 = 11

Also, there is a constant ratio in y. For example,

  • 480 / 120 = 4
  • 120 / 30 = 4
  • 30 / 7.5 = 4

So, from this observation we can conclude that the the set of data shown above displays exponential behavior.

Therefore, my answer is Yes. It displays exponential behavior.

The graph in figure a is also attached below for visual aid.

                                         Question # 8

Answer:

No. It does not display exponential behavior.

To determine:

We have to determine whether the set of data shown above displays exponential behavior. Write Yes or No. Explain why or why not

Solution Steps:

Considering the set of data

x                    21                    18                    15                    12

y                    30                   23                   16                     9

To determine whether the set of data shown above displays exponential behavior, we would first need to check the pattern of x and y values.

The set of data will be exponential if

  • there is a constant change in x
  • there is a constant ratio in y

From the data set, it is clear that there is a constant change in the values of x. For example,

  • 21 - 3 = 18
  • 18 - 3 = 15
  • 15 - 3 = 12

BUT! there is NOT a constant ratio in y. For example,

  • 30 / 23 = 1.30
  • 23 / 16 = 1.44
  • 16 / 9 = 1.78

INSTEAD, there is a constant change in y values. i.e. 30 - 7 = 23, 23 - 7 = 16, 16 - 7 = 9 ; meaning it represents LINEAR BEHAVIOR.

So, from this observation we can conclude that the the set of data shown above DOES NOT display exponential behavior. Instead, it displays LINEAR Behavior because there is constant change in x and y values.

Therefore, my answer is No. It does not display exponential behavior.

The graph in figure b is also attached below for visual aid.

Consider the function.
Verdich [7]

It looks like you're given

f(x) = 1012x^{101} - 72x^{75} + \pi x^2 - e^{2x} + 100346

and are asked to find the 102nd derivative of f(x).

Recall the power rule: for integer n,

\displaystyle \left(x^n\right)' = nx^{n-1}

This means that the power of x reduces to 0 after differentiating n times, and you're left with a constant coefficient n! :

• after differentiating 2 times,

\left(x^n\right)'' = \left(nx^{n-1}\right)' = n(n-1)x^{n-2}

• after differentiating 3 times,

\left(x^n\right)^{(3)} = \left(n(n-1)x^{n-2}\right)' = n(n-1)(n-2)x^{n-3}

• and so on, up to the n-th time, which yields

\left(x^n\right)^{(n)} = n(n-1)(n-2)\cdots\times2\times1x^{n-n} = n!

As soon as you have a constant, the next derivative will be 0. This means that after differentiating 102 times, the first 3 terms of f(x), as well as the constant term, will vanish.

Recall the chain rule:

\bigg(f(g(x))\bigg)' = f'(g(x)) \times g'(x)

Then the first few derivatives of the exponential term are

\left(e^{2x}\right)' = e^{2x} \times (2x)' = 2e^{2x}

\left(e^{2x}\right)'' = 2\left(e^{2x}\right)' = 2^2e^{2x}

\left(e^{2x}\right)^{(3)} = 2^2\left(e^{2x}\right)' = 2^3e^{2x}

and so on, with n-th derivative

\left(e^{2x}\right)^{(n)} = 2^ne^{2x}

Putting everything together, we have

\boxed{f^{(102)}(x) = -2^{102}e^{2x}}
