5-123.
1. The function $f(x)=3x−5$.

The domain is any value of $x$ that yields a real number value for $y$.

1. The sequence $t(n)=3n−5$.

Keep in mind that this is a sequence, not a function.

$1, 2, 3...$

1. The function $f(x) =\frac { 5 } { x }$.

Can $5$ be divided by any number?

$x$ cannot equal zero.

1. The sequence $t(n)=\frac{5}{n}$.

Keep in mind that this is a sequence, not a function.
