If `y=f(x)=(x+2)/(x-1) (x ne 1, -2)` then show that `x=f(y)`

If y = f(x) = (x+2)/(x-1) , x ne1 , then show that x = f(y) .

If f(x) = (1)/(2x-1) , x ne (1)/(2) , then show that : f(f(x)) = (2x-1)/(3-2x) , x ne (3)/(2)

If y=f(x)=(x+1)/(2x+3), where x ne -(3)/(2) , show that: f(y)=(3x+4)/(8x+11) .

If y = (x +2)/( x +1) , y ne 1, then x equals

" If the function "f:R rarr R" defined by "f(x)=(3^(x)+3^(-x))/(2)," then show that "f(x+y)+f(x-y)=2f(x)f(y)"

If f(x)=(x)/(x-1)=(1)/(y) then the value of f(y)

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