Consider the Solow growth model, where population grows at the constant rate n, N=(1+n)N, s = saving rate, the production function is given by Y=zF(K,N), the evolution of capital is given by K=(1-d)K+I where d = depreciation rate and I = investment. The income expenditure identity is given by Y = C+I and S=I. Please upload pictures of your graphical analysis.

What is the key result of the Solow model, show graphically and explain in words.
