1.Let f(x)=x+1x−1f(x) = \frac{x+1}{x-1}f(x)=x−1x+1 for all x≠1x \ne 1x=1. Let f1(x)=f(x)f^1(x) = f(x)f1(x)=f(x), f2(x)=f(f(x))f^2(x) = f(f(x))f2(x)=f(f(x)) and generally fn(x)=f(fn−1(x))f^n(x) = f(f^{n-1}(x))fn(x)=f(fn−1(x)) for n>1n > 1n>1. Let P=f1(2)⋅f2(3)⋅f3(4)⋅f4(5)P = f^1(2) \cdot f^2(3) \cdot f^3(4) \cdot f^4(5)P=f1(2)⋅f2(3)⋅f3(4)⋅f4(5).
