@jim_thompson5910  would you happen to know? im thinking this is not a function since the answer could vary.

jim_thompson5910 · Answer

what is the input here?

anonymous · Answer

the input would be the date,month,year

jim_thompson5910 · Answer

so basically the date, yes

jim_thompson5910 · Answer

the output is the temperature for that given date

anonymous · Answer

haha yes.

jim_thompson5910 · Answer

now if the output is say, the average temperature, then each input would have exactly one output

jim_thompson5910 · Answer

but you make a great point, the temperature in general fluctuates throughout the day

anonymous · Answer

yes

jim_thompson5910 · Answer

so the key word is "average" but they didn't write that in

anonymous · Answer

thats what i was thinking like one person may say the temperature is 52 degrees and another may say its only 49 degrees.

jim_thompson5910 · Answer

so I agree with what you got

anonymous · Answer

so it cant be a function. now would it not be a function because atleast one input results in more than one output?

jim_thompson5910 · Answer

correct

jim_thompson5910 · Answer

if they put "average" in there, then it would be a function

anonymous · Answer
