Question

In the following table, elevation is the input and amount of snowfall is the output.

Elevation (in feet) Snowfall (in inches)
2000 4

3000 6

4000 9

5000 12
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

Answer 1

B. Yes, each amount of snowfall is paired with one elevation.

Answer 2

Option B. is the answer.

Explanation:

In the table, elevation is the input and amount of snowfall is the output.

It means when we put the value of elevation in the given function that represents the whole relation, we get the value of snowfall.

To represent any function for each value of input we should get a different value for output. In this situation each amount of snowfall is paired with one elevation.

Therefore Option B. is the answer.
