1. **State the problem:**
We are given the quadratic function $$f(x) = -0.04x^2 + 0.48x - 0.8$$ representing the company's expected net worth over time in years.
2. **Find when the net worth is zero:**
The equivalent factored form is $$f(x) = -0.04(x - 2)(x - 10)$$.
3. **Use the factored form to find zeros:**
Set $$f(x) = 0$$:
$$0 = -0.04(x - 2)(x - 10)$$
Since $$-0.04 \neq 0$$, we have:
$$(x - 2)(x - 10) = 0$$
This gives two solutions:
$$x - 2 = 0 \Rightarrow x = 2$$
$$x - 10 = 0 \Rightarrow x = 10$$
4. **Interpretation:**
The company's expected net worth is zero after **2 years** and after **10 years**.
5. **Find the maximum expected net worth:**
The vertex form is given as:
$$f(x) = -0.04(x - 6)^2 + 0.64$$
6. **Identify the vertex:**
The vertex of a parabola in form $$a(x - h)^2 + k$$ is at $$(h, k)$$.
Here, $$h = 6$$ and $$k = 0.64$$.
7. **Interpretation:**
The maximum expected net worth is $$0.64$$ million dollars, which occurs after **6 years**.
**Final answers:**
- The company's expected net worth is zero after **2** years and after **10** years.
- The company's maximum expected net worth is **0.64** million dollars, which occurs after **6** years.
