Describe an everyday situation between variables that is a f

Describe an everyday situation between variables that is a function. Clearly explain why the relationship is a function. Then Describe an everyday situation between variables that is NOT a function. Clearly explain why the relationship is NOT a function.

Solution

Solution:

Situation which is function:

Let x be the x th day

and y be the no. of clothes on that day

So, function from x to y is the no. of clothes on that day

We know that for each day, we have fixed no. of clothes

So, this situation is function

Situation that is not function

x = age of a person

y = weight of that person

It is not a function as person of same age can have different weights.
