Explain how to find reasonable domain values for a function
Oksi-84 [34.3K]
A reasonable domain and range is the set of values that exist for the function. The sets that are not reasonable are not considered domain and range. For instance, f(x) = 15√(x - 3) 
The reasonable domain is {x | R, x ≥ 3} since you can't have negative value inside the radicand. 
The reasonable range is {f(x) | R, f(x) ≥ 0} since the minimum value is 0 [Noting that x = 3 gives f(3) = 15√(3 - 3) = 15√0 = 0]

When you are trying to find the mean in a dot plot do you want to use the number of dots of the actual number underneath of the
yuradex [85]

The number of dots tells us how many times we need to add the actual number underneath the dots. So you need to use both.

<h3>Which number should you use for the mean?</h3>

Let's suppose we have the next set:

{2, 2, 2, 4, 5, 5, 6}

If you graphed it in a dot plot, then you will have:

  • 3 dots above the number 2.
  • 1 dot above the number 4.
  • 2 dots above the number 5.
  • 1 dot above the number 6.

A total of 7 dots.

To find the mean, we just compute:

M = \frac{2 + 2 + 2 + 4 + 5 + 5 + 6}{7} = 3.7

So the number of dots tells us how many times we need to add the actual number underneath the dots. In conclusion, to find the mean you need to use both, the number of dots and the number underneath.
