Does this situation describe a function?
a.
no, each amount of snowfall is paired with only one elevation
b.
yes, each amount of snowfall is paired with one elevation.
c.
yes, all the snowfall values are different.
d.
no, all the elevation values are different

This cannot be answered without the table. If each snowfall value is different for each elevation, then it does represent a function. That is, if I have 2000ft (4inches), 4000ft (5 inches), 5000ft (6inches). This represents a function because each Y-value (inches) is unique. If I have 2000ft (4 inches), 4000ft (5 inches), 5000ft (4 inches), this does NOT represent a function because "4 inches" is duplicated.

Assuming this is the same as the other question I just answered and all of the snowfall inches are unique then the answer is C.

This is a robot. try again lol. maybe you attached the wrong image.
