how to find vertical asymptote for the function y=(x+1)/(x^3-4x^2+4x)

To find the vertical asymptotes for the function \( y = \frac{x + 1}{x^3 - 4x^2 + 4x} \), follow these steps:

### Step 1: Factor the denominator
The vertical asymptotes occur where the denominator is equal to zero (since division by zero is undefined), but only if the factor does not cancel with the numerator.

We first factor the denominator \( x^3 - 4x^2 + 4x \):

Factor out the greatest common factor:

\[
x^3 - 4x^2 + 4x = x(x^2 - 4x + 4)
\]

Now, factor \( x^2 - 4x + 4 \):

\[
x^2 - 4x + 4 = (x - 2)(x - 2) = (x - 2)^2
\]

So, the denominator becomes:

\[
x(x - 2)^2
\]

### Step 2: Solve for the values of \( x \) that make the denominator zero
Set the denominator equal to zero:

\[
x(x - 2)^2 = 0
\]

Solve for \( x \):

1. \( x = 0 \)
2. \( (x - 2)^2 = 0 \Rightarrow x = 2 \)

Thus, the denominator is zero when \( x = 0 \) and \( x = 2 \).

### Step 3: Check for common factors between the numerator and denominator
Now, check if any of these factors cancel with the numerator.

The numerator is \( x + 1 \), which does not cancel with any of the factors in the denominator \( x(x - 2)^2 \).

### Step 4: Identify the vertical asymptotes
Since none of the factors in the denominator cancel with the numerator, the vertical asymptotes occur at the points where the denominator equals zero. Therefore, the vertical asymptotes are at:

\[
x = 0 \quad \text{and} \quad x = 2
\]

### Final Answer:
The vertical asymptotes for the function are at \( x = 0 \) and \( x = 2 \).
