What are the types of good in the demand curve?

Some types of good are as follows:

• Normal good:

When incomes of consumers/households increase the quantity demanded would increase also for instant the demand curve would shift to right.

• Inferior good:

When incomes of consumers/households increase the quantity demanded would go down as example the demand curve would shift to left.

• Giffen good:

When the price of the good or service increases the quantity demanded would increase also and vice versa as like an example of an upward sloping demand curve.
