Question
You are given the following economic functions:pQpQ219;313621Where P is the market price for a particular good and Q is the quantity.i) Identify with reasons the demand and supply functions. (3 Marks)ii) Explain the negative intercept of the second function2Q above
Solution
The question seems to be a bit garbled, but I'll try to answer it based on my understanding.
i) The demand and supply functions are typically represented as Qd = f(P) and Qs = f(P) respectively, where Qd is the quantity demanded, Qs is the quantity supplied, and P is the price. The demand function usually has a negative slope, indicating that as price increases, quantity demanded decreases. The supply function usually has a positive slope, indicating that as price increases, quantity supplied also increases.
In your case, the functions seem to be P = 219 - Q and P = 31 + 2Q. The first function has a negative slope, so it is likely the demand function. The second function has a positive slope, so it is likely the supply function.
ii) The negative intercept of the second function, P = 31 + 2Q, means that when the quantity supplied (Q) is zero, the price (P) is 31. This could be interpreted as the minimum price that suppliers are willing to sell the good for. If the price is below 31, suppliers would not supply any of the good. This is a simplification, of course, and in reality, supply functions can be more complex.
