Imagine our classlist as a table $($with about $150$ rows$)$ that looks like this:

a$.$ is the first name of a student a function of the V$-$number? Give a succinct reason

$($one short sentence$)$ why or why not.

b$.$ Say I have looked through the full classlist and tell you that the V$-$number is a

function of the first name. In one sentence in common $($non$-$mathematical$)$ language, what would

that mean? Hint: This would be a bit uncommon for a class this big.
