Answer
A change in consumers' taste shifts the demand curve left or right. IF the consumers taste for a particular good increase, they will demand it more. Any increase in the demand results in the demand curve shifting to the right. Similarly, any decrease in the quantity demanded would result in a leftward shift of the demand curve.
Change in price results into a corresponding change in the quantity demanded. For example, when the price decreases, the quantity demanded would increase for a given demand curve. Similarly when the price increase the quantity demanded would decrease.
Work Step by Step
The shift in the demand curve due to changing consumer taste is demonstrated in the figure attached. It shows that an increase in demand makes the demand curve shift to the right and a decrease to the left.
Also, when price increases, there is a corresponding decrease in the quantity demanded. This change is demonstrated in the figure attached.
