Answer:

D. 16

Step-by-step explanation:

Average rate of change: $\frac{f(a) - f(b)}{a-b}$

Simply plug in 6 for a and 2 for b

Answer:

Step-by-step explanation:

Average rate of change is

f(6) - f(2)

------------------

6-2

f(6) = 2(6)^2 +8 = 2 *36 +8 = 80

f(2) = 2(2)^2 +8 = 2 *4 +8 = 16

80 - 16

------------------

6-2

Determine whether the sequence converges or diverges. If it converges, find the limit. (If an answer does not exist, enter DNE.)

In-s [12.5K]

Answer:

The sequence diverges.

Step-by-step explanation:

A sequence $a_{n}$ converges when $\lim_{n \rightarrow \infty} a_{n}$ is a real number.

In this question, the sequence given is:

$a_{n} = 4n\cos{(7n\pi)}$

The cosine is always going to be between -1 and 1, so for the convergence of the sequence, we look it as: $a_{n} = 4n$ . So

$\lim_{n \rightarrow \infty} a_{n} = \lim_{n \rightarrow \infty} 4n = \infty$

Since the limit is not a real number, the sequence diverges.
