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

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

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

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

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

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

If y=f(x)=(2x-1)/(x-2), then f(y)=

If f(x) = x/(x - 1) = 1/y , then f(y) =

If f(x)=(2^x+2^(-x))/2 , then f(x+y)f(x-y) is equals to (a) 1/2{f(2x)+f(2y)} (b) 1/2{f(2x)-f(2y)} (c) 1/4{f(2x)+f(2y)} 1/4{f(2x)-f(2y)}

If f(x)=(2^x+2^-x)/2 , then f(x+y) f(x-y) is equal to:
