Q:

Which relation is a function?[Control] A. ((-3. 4). (-3.8). (6,8)[Control) B. (6,4).(-3, 8). (6,8)[Control) C. ((-3.4). (3.-8) (3.8)[Control] D. (-3. 4. (3.5). (-3. 8))

Accepted Solution

A:
Answer:I see this "Which relation is a function?A {(-3,4),(-3,8),(6,8)}B {(6,4),(-3,8),(6,8)}C {(-3,4),(3,-8),(3,8)}D {(-3,4),(3,5),(-3,8)}"So the answer is none of these.Please make sure you have the correct problem. Step-by-step explanation:A set of points is a function if you have all your x's are different. Β That is, all the x's must be distinct. There can be no value of x that appears more than once.If you look at choice A, this is not a function because the first two points share the same x, which is -3.Choice B is not a function because the first and last point share the same x, which is 6.Choice C is not a function because the last two points share the same x, which is 3.Choice D is not a function because the first and last choice share the same x, which is -3.None of your choices show a function.If you don't have that choice you might want to verify you written the problem correctly.This is what I see:"Which relation is a function?A {(-3,4),(-3,8),(6,8)}B {(6,4),(-3,8),(6,8)}C {(-3,4),(3,-8),(3,8)}D {(-3,4),(3,5),(-3,8)}"
