Question

A certain bank assigns one unique number to each savings account. The amount of savings in each account depends on how much the owner deposits into the account. The interest paid on each account depends on how much money is in the account. Which of these relations is not a function? (interest paid, savings account number) (interest paid, amount in savings account) (savings account number, interest paid) (savings account number, amount in savings account)

Answer 1

Answer:

(interest paid, savings account number)

Step-by-step explanation:

A certain bank assigns one unique number to each savings account.

The amount of savings in each account depends on how much the owner deposits into the account.

The interest paid on each account depends on how much money is in the account.

A function is a relation in which each input has only one output. In any given relation, y is a function of x, when for each input 'x' there is only one output y.

So, here the relation which is not a function is : (interest paid, savings account number)

Answer 2

All the ones with saving account number are not functions because the outcome does not depend on the account number. It depends on the amount in the account and the interest.
