Question

Which relation does not represent a function?

A- (0,8), (3,8), (1,6)
B- (4,2), (6,1), (8,9)
C- (1,20), (2,23), (9,26)
D- (0,3), (2,3), (2,0)

Please help I really do not understand any of these alternate interior angles and such, I missed 1 day and now i'm way behind.

Answer 1

this has nothing whatsoever to do with angles, interior or otherwise

Answer 2

the ones that have a repeat in the first coordinate are NOT function, if all the numbers in the first coordinate are different, then it IS a function

Answer 3

A relation is only a function only if there is only ONE y coordinate for every x coordinate
Only one of these does not follow this rule

Answer 4

Sorry mate, idk that's just what we were learning about so I assumed. Angles...

Answer 5

So it would be D? Since 3 is a repeating y coordinate

Answer 6

Well it's the x value that can't be the same

Answer 7

Still D right? It has two X coordinates of the same value and as well as Y

Answer 8

Yes
