Question

state the domain of the following relation by selecting one of the symbols to make the given answer correct.
$\\{(r, s): s = \frac{2r-5}{13r}\\}$
domain: $\\{r: r \in \mathbb{r}, r \\: \square \\: 0\\}$

Explanation:

Step1: Identify denominator restriction

For the expression $s=\frac{2r-5}{13r}$, division by zero is undefined.

Step2: Set denominator not equal to 0

$13r
eq 0$

Step3: Solve for valid $r$

Divide both sides by 13: $r
eq 0$

Answer:

$
eq$
Domain: $\{ r: r \in \mathbb{R}, r
eq 0\}$
