kysyntäkurvi
kysyntäkurvi, the Finnish term for a demand curve, is a graphical representation used in microeconomics to illustrate the relationship between the price of a good or service and the quantity demanded by consumers. The curve typically slopes downward from left to right, reflecting the inverse law of demand: as prices rise, the quantity demanded falls, and vice versa. This negative slope arises from three mechanisms – the substitution effect, income effect, and the law of diminishing marginal utility – which together drive consumer choice toward lower-priced alternatives and reduce purchase quantity when prices increase.
Mathematically, a demand curve can be expressed as a function Q = D(P), where Q denotes quantity
