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]
Answer:
B. 23.58
Step-by-step explanation:
I got it right
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:

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.

Answer:
y + 1 = -3 (x + 2)
Step-by-step explanation:
y + 1 = -3 (x +2)
First if you want to check your answer take the answer you got and divided it by one of the other numbers like 457*342=156,294 and then dived 156,294 by 342=475 and that's how you know its correct!:) And how you get the answer
