If f(x) = `( ( x -1 ) / ( x + 1 ) )`, then `f(1/x ) + f( x )` is equal to

If f(x) = 1/x , then f(a)/f(a + 1) is equal to

If f(x)=(x-1)/(x+1) , then f(ax) in terms of f(x) is equal to

If f (x) = (x-1)/( x+1) , then f ((1)/( f (x))) equals

If f(x)=(x-1)/(x+1), then f(f(ax)) in terms of f(x) is equal to (a) (f(x)-1)/(a(f(x)-1)) (b) (f(x)+1)/(a(f(x)-1))(c)(f(x)-1)/(a(f(x)+1))(d)(f(x)+1)/(a(f(x)+1))

If f(x)=(x-1)/(x+1) then f(ax) in term of f(x) is equal to

If f(x) = x^(3) - (1)/(x^(3)) then f (x) + f ((1)/(x)) is equal to

If f(x) = (x-1)/(x+1) , then f(2) is equal to
