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

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

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

If y=f(x)=((x+2))/((x-1)), then (a)x =f(y)(b)f(1)=3(c)y increases with x for x<1(d)f is a rational function of x

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

If y = f(x) = ((x+2))/((x-1)) , then (a) x = f(y) (b) f(1) = 3 (c) y increases with x for x < 1 (d) f is a rational function of x

If the function f(x) satisfies the relation f(x+y)=y(|x-1|)/((x-1))f(x)+f(y) with f(1)=2. then lim_(x rarr1)f'(x) is

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

If f(x) = (( x + 1))/( ( x - 1)) , then the ratio of x to f(y) where y = f(x) is

If f((x)/(y))=(f(x))/(f(y)),AA y,f(y)!=0 and f'(1)=2, find f(x)

If f(x) = (x-1)/(x+1) , then prove that (f(x)-f(y))/(1+f(x)f(y))=(x-y)/(1+xy) .
