Let `f(x)=(alphax)/(x+1),x ne -1`. Then, for what values of `alpha` is f[f(x)]=x?

Let f(x)=(alpha x)/(x+1), x ne -1. Then, for what value of alpha " is " f[f(x)]=x ?

Let f(x)=(alpha x)/(x+1), x ne -1. Then, for what value of alpha " is " f[f(x)]=x ?

Let f(x)=(alpha x)/(x+1), x ne -1. Then, for what value of alpha " is " f[f(x)]=x ?

Let f(x)=(alphax)/(x+1),xne0 , then for what value of alpha is f[f(x)]=x ?

Let f(x)=(alphax)/((x+1)),x!=-1. The for what value of alpha is f(f(x))=x ? (a) sqrt(2) " " (b) -sqrt(2) " " (c) 1 " " (d) -1

If f (x) = (alpha x)/( x+1) , x ne -1 , for what value of alpha is f[f(x)] = x? a) sqrt2 b) -sqrt2 c)1 d)-1

f(x) = (alpha x)/(x + 1) (x ne -1) , then for what value of alpha , f{f(x)} = x?
