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

Are 3:5and 1:2 equivalent

german

Answer:

No. They are not equivalent.

Step-by-step explanation:

$\frac{3}{5} \neq \frac{1}{2}$

=> $\frac{6}{10} \neq \frac{5}{10}$

Therefore, 3/5 and 1/2 are not equivalent.
