1. **Problem Statement:** Find the domain and range of the function $y = \frac{2x+3}{x-1}$.
2. **Domain:** The domain is all real numbers except where the denominator is zero because division by zero is undefined.
3. Set the denominator equal to zero and solve:
$$x - 1 = 0$$
$$x = 1$$
4. So, the domain is all real numbers except $x = 1$.
5. **Range:** To find the range, solve for $x$ in terms of $y$:
$$y = \frac{2x+3}{x-1}$$
Multiply both sides by $x-1$:
$$y(x-1) = 2x + 3$$
$$yx - y = 2x + 3$$
Bring all $x$ terms to one side:
$$yx - 2x = y + 3$$
Factor out $x$:
$$x(y - 2) = y + 3$$
Solve for $x$:
$$x = \frac{y + 3}{y - 2}$$
6. The expression for $x$ is undefined when the denominator is zero:
$$y - 2 = 0$$
$$y = 2$$
7. Therefore, the range is all real numbers except $y = 2$.
**Final answers:**
- Domain: $\{x \in \mathbb{R} \mid x \neq 1\}$
- Range: $\{y \in \mathbb{R} \mid y \neq 2\}$
