To effectively graph a mathematical equation or function, Mr. Andersen recommends following these important requirements:

1. Knowledge of the equation: Understand the equation or function you are graphing, including its form, variables, and any restrictions or conditions. This will help you determine the behavior and shape of the graph.

2. Domain and range: Determine the valid values for the x and y coordinates. The domain refers to the set of all possible input values (x-values) of the equation, while the range refers to the set of all possible output values (y-values). Identifying the domain and range helps define the boundaries of the graph.

3. Scale and labeling: Choose appropriate scales for the x and y axes to represent the range of values in the equation. Label the axes clearly to indicate the units or values represented.

4. Marking key points: Identify and plot critical points on the graph, such as the x and y-intercepts, local maximums and minimums, points of symmetry, and any other relevant points. These points help to visualize the behavior of the function.

5. Shape and symmetry: Determine the overall shape of the graph based on the mathematical equation. Analyze if it is linear, quadratic, exponential, trigonometric, or any other shape. Also, determine if the graph exhibits any symmetry, such as being symmetric about the x-axis, y-axis, or origin.

6. Intercepts and asymptotes: Identify any x or y-intercepts, which are the points where the graph crosses the x or y-axis, respectively. Additionally, locate any vertical or horizontal asymptotes, which represent lines that the graph approaches but never crosses as the x-values approach certain values.

7. Miscellaneous features: Depending on the equation, there might be additional graph features to consider. For example, if the equation is periodic, identify the period and graph multiple cycles. If the equation is piecewise-defined, graph each defined segment separately.

By adhering to these requirements, you will be able to accurately graph a mathematical equation and gain a better understanding of its behavior and properties.
