Answer:

<h3>There are 8! ways to answer.</h3>

Step-by-step explanation:

We know that the survey has 8 items, that means we can use the factorial number, because it's a simple permutation.

Using a factorial we have

n! where n=8, which is the total number of items.

8! = 8\times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 = 40,320

Therefore, there are 40,320 ways to answer the survey, or 8! ways.

The area is the sum of 'n' rectangle areas.
The width of the rectangle is size of interval, (domain size)/n
The height of each rectangle is f(interval) as interval moves along domain.

For this example, domain size = 3-1 = 2
size of interval = 2/n
height varies from f(1) to f(3), increasing by 2/n each time.
f(1+(2/n)i)

Putting this together, the area is the sum of:
\frac{2}{n}*f(1+\frac{2i}{n})

Since you are given the function f(x). Sub input into f(x) to get area in terms of n and i.

f(1+\frac{2i}{n}) = \frac{3(1+\frac{2i}{n})}{(1+\frac{2i}{n})^2 +8} \\  \\ =\frac{3n+6i}{n}*\frac{n^2}{(n+2i)^2 +8n^2} \\  \\ =\frac{3n^2 +6ni}{9n^2+4ni+4i^2}

Finally, the summation is:
\frac{2}{n}*\frac{3n^2 +6ni}{9n^2+4ni+4i^2} = \frac{6n +12i}{9n^2+4ni+4i^2} \\  \\  A =\lim_{n \to \infty} \sum_{i=1}^n \frac{6n +12i}{9n^2+4ni+4i^2}
