A Giffen good is a good whose consumption increases as its price increases. (For a normal good, as the price increases, consumption decreases.) Thus, the demand curve will be upward instead of downward sloping.
A giffen good has an upward sloping demand curve because it is exceptionally inferior. It has a strong negative income elasticity of demand such that when a price changes the income effect outweighs the substitution effect and this leads to perverse demand curve.

Because of the law of demand the demand curve always slopes?
given that the demand curve is for a normal good then this is the case as prices increase people will be willing to consume less of the good. If the good is a giffen good then this will not be the case an in fact the demand curve may either remain straight or will curve upwards as prices increase.
Why would demand curve slope upward?
The Law of Demand states that price and quantity demanded are inversely related. This means that for a normal good, the demand curve slopes downward. A demand curve might slope upward in the event that instead of being a normal good, we could be witnessing a so-called Giffen good. The existence of Giffen goods is debatable, but in theory they can be shown to be possible. The rationale for the upward sloping demand curve is due to the real income effect on a basket of goods when one (or some) of the goods exhibits a price reduction. Under normal conditions, the reduction in price would allow you to purchase more of that good. However, if this is a Giffen good, the consumer will consume less of it in order to purchase more of another good. This is not to be confused with an inferior good, for which a reduction in price leading to an increase in purchasing power results in substituting an inferior good (hamburger) in favour of a normal good (steak). This causes a shift in the demand curve. For Giffen goods, no close substitute would cause the consumer to spend less on the cheaper good in order to purchase more of a non-substitute good, say, pencils wherein the cost of rice is reduced.
What is a positive demand curve?
demand curve tends to be downward sloping (negative) for normal goods. for goods that are perceived to be of superior value to customer (like it serves as a status quo), the higher the price, the higher the quantity demanded. hence, giving a positive demand curve. there are called the veblen goods. Giffen goods also has a positive demand curve.
Assuming increase a price of commodity X where x is an inferior good decompose the total effect of price change into substitution n income effect also derive the demand curve?
decompose total effect of price increase for an inferior good and giffen into substitution and income effect, in each case derive both the ordinary and compensated demand curve
What are Giffen and Veblen goods?
Giffen and Veblen goods are examples of the violation of the law of demand. For these two commodity types, as price increases, so does demand for them.

Why engel curve slopes negatively downward in case of giffen goods?
The Engel curve shows how household expenditure on goods changes with rising income. Giffen goods are inferior goods. As household income rises, instead of consuming more of the Giffen goods, expenditure is switched to better quality goods. Consequently, the demand for a Giffen good falls as income rises and this results in a downward sloping curve. Incidentally, a curve that slopes "negatively downward" is actually a curve that slopes positively upwards!

decompose total effect of price increase for an inferior good and giffen into substitution and income effect, in each case derive both the ordinary and compensated demand curve

Why is the ordinary demand curve flatter than a compensated demand curve if the good is a normal good but the reverse is the case if the good is inferior?
because the ordinary demand curve ignores the income effect of price changes.also since the compensated demand curve is less inelastic than an ordinary demand curve.
What are the difference between giffen good and inferior good with 3 examples?
All Giffen goods are inferior goods. But not all inferior goods are Giffen goods. For inferior goods, the negative substitution effect will more than offset the positive income effect, so that total price effect will be negative. For Giffen goods, the positive income is positive and very strong that the law of demand does not hold. Price elasticity of Giffen good is positive. Inferior Goods: Cheap goods Giffen Goods: Rice, wheat, noodles are Giffen goods in China
How do you show on a demand curve an increase in the demand for a good?
You can choose to shift the demand curve to the right i.e. expansion of demand.
