If `f(x)=(x)/(x-1)`, then evaluate : `(f(a//b))/(f(b//a))`

If f(x)=(x-1)/(x+1) , then prove that: (f(b)-f(a))/(1+f(b)*f(a))=(b-a)/(1+ab)

If f(x)=x^(2) , then evaluate : (f(x+1)-f(x-1))/(4x)

If f(x)=ax^(2)+bx+c and f(x+1)=f(x)+x+1 , then the value of (a+b) is __

If f(x)=(x-a)^2(x-b)^2 , find f(a+b)

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

If f(x)=log((1-x)/(1+x)) , show that f(a)+f(b)=f((a+b)/(1+ab))

f(x)=x/(x-1) then (f(a))/(f(a+1)) is equal to a. f(-a) b. f(1//a) c. f(a^2) d. f(-a/(a-1))

If f(x)=log_e((1-x)/(1+x)); prove that f(a)+f(b)=f((a+b)/(1+a b))

If f(x)=x^3-frac{1}{x^(3)} find the value of f(x)+f(frac{1}{x})

If a, b (altb) be the points of discontinuity of function f(f(f(x))) , where f(x)=1/(1-x),x!=1 , then int_a^b f(x)/(f(x)+f(1-x))dx= (A) 0 (B) 1/2 (C) 1 (D) 2
