To find the vertical asymptote(s) of the function $r(x) = \frac{4x + 1}{x - 3}$, we follow these steps:

Step 1: Identify the denominator.

A vertical asymptote occurs where the function is undefined, which happens when the denominator is equal to zero.

For the function $r(x) = \frac{4x + 1}{x - 3}$, the denominator is $x - 3$.

Step 2: Set the denominator equal to zero and solve.

$x - 3 = 0$ Solving for $x$: $x = 3$

Conclusion:

The vertical asymptote of the function is at $x = 3$.

Tip: Always check both the numerator and the denominator for any common factors before finding vertical asymptotes. If they cancel out, there may not be a vertical asymptote at that point.
