## Function Analysis and Contour Maps

Consider the function \( f(x, y) = \sqrt{x^2 y} \).

### Task a: Domain of \( g \)
We need to sketch or describe the domain of the function \( g \).

The domain is given by:
\[ \text{Domain} = \{ (x, y) \mid y \geq 0 \} \]

This means the function is defined for all values of \( x \) and \( y \) where \( y \) is greater than or equal to zero.

### Task b: Contour Map
You are asked to sketch a contour map (level curves on one set of axes) for \( z = 1, 2, 3 \). 

To visualize this, you can use the following link to an online graphing tool:
[Desmos Calculator](https://www.desmos.com/calculator/lqsz6yuywz)

The contour map will represent the level curves of the function for different values of \( z \). For each \( z \), the contour represents the set of points \((x, y)\) where \( f(x, y) = z \).

By inputting the function into the graphing tool, you can explore the level curves for specific values of \( z \) such as 1, 2, and 3. This aids in understanding how the function behaves and the shape of the contours in its domain.
