The domain is all of the x - values, while the range is all of the y - values. If there are two point with the same x - values, then it is not a function. Therefore, your answer would be A.
Hope this helped, and have a nice day!

Domain (ur x values) are {-4,-1,1,4}
range (ur y values) are {-1,1,4}..if u have repeating numbers, u only have to write them once
yes, this is a function because there are no repeating x values

Answer:

n = 6 $\sqrt{3}$

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = $\frac{\sqrt{3} }{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{n}{12}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2n = 12 $\sqrt{3}$ ( divide both sides by 2 )

n = 6 $\sqrt{3}$

Alenkasestr [34]

<h3>Solution:</h3>

$1. \space\ V_{Rectangular \space\ prism} = 10 \text\] units^{3}\\\\2. \space\ L_{Small \space\ cube} = \frac{1}{2} \space\ units\\\\ 3. \space\ V_{Small \space\ cube} = L ^{3}$
