Answer:
No, the relation is not a function.
Step-by-step explanation:
We know, 'A function is a relation which maps each point of the domain to a unique image'.
It is given that, the relation is 'f(x) = temperature in Seattle Washington on that date' and the domain is '{x| x is a date, expressed in day/month/year}'.
Now, as the temperature does not remain same throughout the day.
So, we get that,
'For the same date, the value of f(x) is not unique'
Thus, the given relation is not a function.
