Can someone please explain what does these questions mean?

Design a wine glass that uses at least 5 different equations to form the outline of the shape. At least half of your equations must be curves. It is easier if the design is done with the glass on its side, that is, with the axis of the design running along
the x-axis

Produce an accurate graph of your design. A sketch of the final product would be appropriate

Submit a list of the equations you have used in the design. Include any domain
restrictions.

Be sure to include all working and justification in the development of your design

These questions are from an assignment or project task that requires you to design a wine glass using mathematical equations. Here's an explanation of what each question means:

1. Design a wine glass that uses at least 5 different equations to form the outline of the shape:
- You need to create a shape that looks like a wine glass using mathematical equations.
- The shape should be formed by at least 5 different equations.
- At least half of the equations should be curves. This means that the equations should describe curved lines or shapes.

2. It is easier if the design is done with the glass on its side, with the axis of the design running along the x-axis:
- When creating the design, it is recommended to draw the wine glass on its side.
- The axis of the design should be aligned with the x-axis, which means the glass would be lying horizontally.

3. Produce an accurate graph of your design. A sketch of the final product would be appropriate:
- After constructing the equations for the wine glass design, you need to plot these equations on a graph.
- The graph should accurately represent the shape of the wine glass.
- You can also provide a sketch of the wine glass design to demonstrate the final product visually.

4. Submit a list of the equations used in the design. Include any domain restrictions:
- You need to make a list of all the equations you used to create the wine glass design.
- Additionally, if there are any specific restrictions on the domain (permissible values) for each equation, you should include these in the list.
- For example, if an equation only works for a certain range of x-values, you should mention this as a domain restriction.

Lastly, the prompt emphasizes that you should include all your working process, reasoning, and justifications throughout the development of your design. This means explaining how you arrived at the equations, any adjustments or modifications you made, and any mathematical principles or rules that guided your design choices.
