Support Class 2. 1. On the same graph, plot the following functions: (i) y=1+x; (ii) y=2+x; (iii) y=1+2x. Explain how the graphs of (ii) and (iii) di/er from the graph of (i). 2. On the same graph plot the following functions y = 1 + x y = 9 x: Solve mathematically for the point where these two functions intersect. y = 3 + x: On the same graph, plot this new line. Solve mathematically for the point of intersection between the functions y = 3 + x y = 9 x Suppose instead the second function shifts down so that y = 7 x: Solve math- ematically for the point of intersection between the functions y = 1 + x y = 7 x Explain how shifts in these functions a/ect the point of intersection. 3. On the same graph, plot the following functions

Unformatted text preview: q = 9 & p (Demand) q = 1 + p (Supply) (in this case you may put q on the y-axis). The equilibirum price p & is the price where supply equals demand. Find the equilibrium price and the quantity traded. (a) Suppose supply increases to q = 3 + p: Find the equilibrium outcome assuming the demand curve described above. Draw a diagram which depicts your answer. (b) Suppose instead demand falls to q = 7 & p: Find the equilibrium outcome assuming the supply curve described above. Draw a diagram which depicts your answer. (c) Flip your diagrams in (a) and (b) so that p is now on the y-axis. Explain how market price adjusts to shifts in demand and supply. 1...
