1. **State the problem:** We are given the rational function $$f(x) = \frac{x^2(x - 2)}{(x + 1)(x - 2)}$$ and asked to analyze its properties including vertical asymptotes, horizontal/slant asymptotes, intercepts, and holes.
2. **Simplify the function:** Notice that the factor $(x - 2)$ appears in both numerator and denominator. We can cancel it out except where it causes a hole.
$$f(x) = \frac{x^2\cancel{(x - 2)}}{(x + 1)\cancel{(x - 2)}} = \frac{x^2}{x + 1}, \quad x \neq 2$$
3. **Vertical asymptotes:** Vertical asymptotes occur where the denominator is zero and the factor is not canceled.
Set denominator to zero:
$$x + 1 = 0 \implies x = -1$$
So, there is a vertical asymptote at $x = -1$.
4. **Hole:** The canceled factor $(x - 2)$ causes a hole at $x = 2$.
Find the $y$-value of the hole by substituting $x=2$ into the simplified function:
$$f(2) = \frac{2^2}{2 + 1} = \frac{4}{3}$$
So, there is a hole at $(2, \frac{4}{3})$.
5. **Horizontal or slant asymptote:** Since the degree of numerator (2) is one more than denominator (1), there is a slant asymptote.
Perform polynomial division:
$$\frac{x^2}{x + 1} = x - 1 + \frac{1}{x + 1}$$
So, the slant asymptote is:
$$y = x - 1$$
6. **x-intercept:** Set numerator equal to zero (using simplified function):
$$x^2 = 0 \implies x = 0$$
So, the x-intercept is at $(0,0)$.
7. **y-intercept:** Evaluate $f(0)$:
$$f(0) = \frac{0^2}{0 + 1} = 0$$
So, the y-intercept is also at $(0,0)$.
**Final summary:**
- Vertical asymptote at $x = -1$
- Hole at $(2, \frac{4}{3})$
- Slant asymptote $y = x - 1$
- x-intercept and y-intercept at $(0,0)$
