1. The problem is to understand and describe the graph of the function $y = x^x$.
2. The function $y = x^x$ is defined for $x > 0$ because for real numbers, raising a negative number to a real power can be undefined or complex.
3. The function can be rewritten using exponentials and logarithms as:
$$y = x^x = e^{x \ln x}$$
4. To analyze the graph, consider the domain $x > 0$.
5. At $x=0$, the function is not defined, but the limit as $x \to 0^+$ is:
$$\lim_{x \to 0^+} x^x = \lim_{x \to 0^+} e^{x \ln x} = e^0 = 1$$
6. At $x=1$, $y = 1^1 = 1$.
7. To find extrema, differentiate:
$$y' = \frac{d}{dx} e^{x \ln x} = e^{x \ln x} \cdot \frac{d}{dx} (x \ln x) = x^x (\ln x + 1)$$
8. Set derivative to zero for critical points:
$$x^x (\ln x + 1) = 0 \implies \ln x = -1 \implies x = e^{-1} = \frac{1}{e} \approx 0.3679$$
9. At $x = \frac{1}{e}$, the function has a minimum.
10. The minimum value is:
$$y\left(\frac{1}{e}\right) = \left(\frac{1}{e}\right)^{\frac{1}{e}} = e^{-\frac{1}{e}} \approx 0.6922$$
11. For $x > 1$, the function increases rapidly.
12. Summary: The graph of $y = x^x$ is defined for $x > 0$, approaches 1 as $x \to 0^+$, has a minimum at $x = \frac{1}{e}$ with value approximately 0.6922, and increases rapidly for $x > 1$.
Final answer: The graph of $y = x^x$ is an increasing curve for $x > 0$ with a minimum at $x = \frac{1}{e}$.
