I am working on a Wikipedia page that compares several common utility functions. Although I found some information about these topics on the web, I didn't find it all in one place, and often got confused by the different terms. I will be happy for any comments or reviews. Most importantly: are the facts in this page correct?
EDIT: to make the question self-contained, I copy its current contents below. Because StackExchange markdown does not support tables, I used Senseful Solutions to create the text table.
This page compares the properties of several typical utility functions of divisible goods. These functions are commonly used as examples in consumer theory.
The utility functions are exemplified for two commodity types, $x$ and $y$. $p_x$ and $p_y$ are their prices. $w_x$ and $w_y$ are constant parameters.

| Name | Function | Indifference curves | Demand curve | Monotonicity | Convexity | Good type | Example |
+---------------+-------------------------------------+-----------------------+-----------------------------------------------------------------------------------+----------------+-------------+-----------------------------------------+----------------------------------+
| Linear | ${{x\over w_x}+{y\over w_y}}$ | Straight lines | Step function: only goods with minimum ${w_i p_i}$ are demanded | Strong | Weak | Substitute good|perfect substitutes | Potatoes of two different farms |
| Leontief | $\min({x\over w_x},{y\over w_y})$ | L-shapes | hyperbolic: ${\text{Income} \over w_x p_x+w_y p_y}$ | Weak | Weak | Complementary good|perfect complements | Left and right shoes |
| Cobb–Douglas | $x^{w_x} y^{w_y}$ | hyperbolic | hyperbolic: $\frac{w_x}{w_x+w_y} {\text{Income} \over p_x}$ | Strong | Strong | Independent good|independent | Apples and socks |
| Maximum | $\max({x\over w_x},{y\over w_y})$ | ר-shapes | Discontinuous step function: only one good with minimum ${w_i p_i}$ is demanded | Weak | Concave | Substitute good|substitutes | ? |

Are the details in the table correct?
EDIT: Many thanks to all commenters and answerers. I revised the page accordingly.
