The relation which is a function is; Choice A;<em> {(6, −4), (5, 8), (−3, 6), (−4, −4)}</em>
<h3>What is a function?</h3>
In mathematics, a function from a set of values for variable x to a set of values for variable y assigns to each element of x only one element of y. The set X is called the domain of the function and the set Y is called the codomain of the function.
On this note, since in Choice A, each x-value is mapped distinctively to one value of y, Choice A is a function.

Alan is 14 years old
He is twice as old as James
then Alan is the elder brother
Alan is twice as old means his age is double the age of James
Alans age = 2 x james age
that means James must be half of Alans age
Alans age = 14 years
James age = 14 / 2 = 7 years
therefore James is 7 years old
Answer:
Yes
Step-by-step explanation:
Dan used 2 and 6, and after 3 and 9. If you multiply 2×1.5 = 3, and 6×1.5 = 9, so the ratio is the same and is equal to 1.5
I hope this helps, I tried to make my handwriting as easy to read and to explain as much, I just used a calculator to compute all those values to find AC
The correct answer is 16x^3-32x+3. really hope this helps lmk if you need an explanation. please mark me brainliest
