Q.9. The price of a product f(x,y) depends on the price (x) of the raw materials and the price (y) of transportation of the product to the market according to: f.R2→R f(x,y)=x²+xy+y² If the rate of change of the price of the product along the direction of the vector (1,m) is 1 [ka+lb], when the price of raw material is a and the price of transportation of the product to the market is b, then find the value of 2k-1²k-1.
