C?

Answer 4

mhmm for it to be a one-to-one function that means there can't be another account number with the same bank balance

Answer 5

For it to be a function. it would have to pass the vertical line test

so basically, as long as there are no two accounts with the same account number, you're fine
but difference accounts can have the same balance

Answer 15

but A says it's not a function

it's a function as long as it passes the vertical line test
but for it to be a one-to-one function, it has to also pass the horizontal line test
