Demand = Price = Marginal Cost.
yes the demand curve is perfectly inelastic and horizontal
perfectly elastic demand function.
No it does not. Only Perfectly Competitive firms have a horizontal Marginal Cost curve, which is also there demand curve.
Because for a perfectly competetive firm since the demand curve is perfectly elastic even a slightest price change doesnt add any further demand..so there is no change in marinal revenue also.Since revenue is demand multiplied with cost of unit..the two curves are same.
the demand curve for a good is very unlikely to be perfectly vertical because

When supply and demand are perfectly elastic/inelastic
The demand curve would be perfectly elastic.
the same as the market demand curve.
Since a firm in a perfectly competitive market is a passive price taker, the demand curve for the individual firm is a horizontal line. This means that the firm receives the same price for any level of output. This therefore means that Margincal Revenue curve and Average revenue curve is the same as the demand curve. D=P=MR=AR For example, the price facing a particular firm (perfectly competitive) is $2. If the firm sells two pens it receives a total revenue of $4, if it sells 3 pens, then $6 and so on. $4/$2=2 $6/$2=2
When demand curve intersects the supply curve.
Wheat is virtually a perfectly competitive market. Therefore, its demand curve is horizontal. The only thing that could change the market price of wheat flour is a shift in the demand curve, e.g. a shift in consumer tastes.
A perfectly competitive firm's supply curve is that portion of its' marginal cost curve that lies above the minimum of the average variable cost curve. A perfectly competitive firm maximizes profit by producing the quantity of output that equates price and marginal cost. As such, the firm moves along it's marginal cost curve in response to alternative prices. Because the marginal cost curve is positively sloped due to the law of diminishing marginal returns, the firm's supply curve is also positively sloped.
