Supply and Demand

I don’t understand what is supposed to be done. :’/

I can't see the picture it's too blurry but I hope this example can help with the definition

Definition:

Supply is the amount of the good that is being sold onto the market by producers. At higher prices, it is more profitable for firms to increase supply, so supply curve slopes upward. Demand is the quantity of the good that consumers wish to buy at different prices. At higher prices, less will be demanded.

Difference:

The paying capacity and the willingness of the buyer at a specific price is demand, while the quantity that is offered by the producers of those goods to its customers or consumers at a specific price is supply.

Relationship:

Supply refers to the amount of goods that are available. Demand refers to how many people want those goods. When supply of a product goes up, the price of a product goes down and demand for the product can rise because it costs loss. At some point, too much of a demand for the product will cause the supply to diminish.

Example:

Meanwhile, a shift in a demand or supply curve occurs when a good's quantity demanded or supplied changes even though price remains the same. For instance, if the price for a bottle of beer was $2 and the quantity of beer demanded increased from Q1 to Q2, then there would be a shift in the demand for beer.
