f"(x)=e^x,, putting f'(x)=0 gives x=0 and f"(0) =1 which means at x=0 the function has a local minima,, The point of local minima is (0,-1).Since this point lies below the origin,, it must cut the x axis which means f(x) =0 for two real values of x
thanks anurag. hope u get into isi. it's better than dse in many ways. solving these jrf papers seems to be a good idea. plus u can look at some of the maths questions from DSE option B question papers. just keep solving problems the way u did for the written test. keep in mind what Amit sir posted about the interview. all the best :)
Since a production function is given, we could perhaps calculate the labor demand from this equation (MPL = real wage). This would have to be equal to the labor supply determined in part 1. Substitute this back into the production function and we should find equilibrium output Y. BUt I'm not sure how Investment will figure in this equation, as this is more of a supply side equation :/ . And I think theta determines the Labor share of income?
