Find the domain of the function `f(x) =(x^2-3x+5)/(x^2-5x+4)`.

Explanation

To find the domain of the function \( f(x) = \frac{x^2 - 3x + 5}{x^2 - 5x + 4} \), we need to determine the values of \( x \) for which the function is defined. The function is a rational function, which means it is defined everywhere except where the denominator is equal to zero.

### Step 1: Identify the denominator
The denominator of the function is:
\[ x^2 - 5x + 4 \]
