5-123.

Describe the domain of each function or sequence below. 5-123 HW eTool (Desmos).

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.
