Of the provided graphs, the second would be the correct answer.
Functions occur when the input only has one possible output (though the output can be recieved through multiple inputs)
4, 8, 12, 16, 20, 24, 28, 32, 36, 40
Hope this helps! ^_^
The answer would have to be A because if it's ROUNDED to the nearest ounce then 2 is closer to 0 so it would be A
That would be A, 22/12 and 27/12
