Desmos design must also include at least one of each of the functions below:

• Polynomial function of even degree (greater than 2)
• Polynomial function of an odd degree (greater than 1)
• Exponential function
• Logarithmic function
• Trigonometric function
• Rational function
• A sum/difference/product or quotient of the two of the above functions
• A composite function
• MAXIMUM of 30 graphs total

The diagrams must be drawn using app.diagrams.net online tool, saved as .png or .jpg file and inserted in the comments.

Part 1. Conceptual Model

Please remember that the Enhanced Entity-Relationship diagram is only a part of your assignment. You need todescribethe Conceptual Model, which must include the following elements:

• Entities and their attributes. For each entity you must also specify unique identifier attribute(s)
• Entity super types and subtypes. Describe inheritance types and the corresponding discriminators.
• Identify multi-valued and composite attributes (if any). In this case, they need to be shown in the ER diagram with the corresponding notations.
• Describe relationships between entities and their cardinalities. Remember that relationships can be one-to-one, one-to-many, many-to-many, and also optional or mandatory

Please share the demos link or screenshots of the graphs with the equations you used to make the image on desmos in your response. Please let me know which types of the above functions you used to help make the image on desmos.

Part 2. Logical Model

Describe the algorithm of convert the Conceptual Model into the Logical Model. Remember that your description should include the following elements:

• Entities in the Conceptual Model become relations (tables) in the Logical Model, and unique identifiers become primary keys.
• For one-to-one or one-to-many relationship between two entities you will need to have a foreign key in one of the relations (tables).
• If there is a many-to-many relationship between two entities, then you will need to have a new relation (table) with a composite primary key
• For each field (column) in a relation, describe a data type (integer, float, character, text etc.)
• If an entity contains a multi-valued attribute, then you will need to draw a new relation in the Logical Model corresponding to this attribute.

1. Delete the existing activities and layouts from your branch to start fresh. In this lab we will be building a "To Do" app.
2. Creat a new empty activity named "MainActivity" by going to File -> New -> Activity -> Empty Activity and update the layout to look like the following: It uses a ListView to take the full height of the activity. Don't worry about the items in the ListView as those will be created later. At the bottom is an EditText with a hint of "Type Here", a switch that says "Urgent" and a button that says "Add".
3. Creat another layout file to be used for each todo item in the ListView. It should only need a TextView, but make sure you increase the text size to at least 20dp to ensure it's easily readable.
4. Creat a new Java object to hold each todo item, it should contain a string with the text of the todo, and a boolean for if it is urgent or not. Creat a List to hold all your items, and for the adapter to use for displaying them.
5. When you click "Add", you should creat a new todo item and add it to the list, clear out the text in the EditText, and call "notifyDatasetChanged()" on your adapter so it refreshes.

Implement a BaseAdapter to power the ListView. In AndroidStudio, type ctrl + O (the letter 'O', not number zero). From the list of inherited functions, implement these ones:
