If `f(x) =lx ^(2) +mx+n,` then the value of `(f(x+3) -f(x))/(f(x+2)-f(x+1))` is-

If f(x)=(x+1)/(x-1) , then the value of f(f(2)) is

If f (x) = x^(2) -2x + 3, then the value of x for which f (x) = f(x +1) is

If f (x) = x^(2) -2x + 3, then the value of x for which f (x) = f(x +1) is

Find the value of f(f(-2)) , if f(x)=(x)/(x+1)

If 2f(x)+3f(-x)=x^(2)-x+1, find the value of f'(1)

If 2f(x).+ 3f(-x) = x^2-x+1, find the value of f(1).

if f(x) = x^n then the value of f(1) - (f'(1))/(1!) + (f''(1))/(2!) + ---+((-1)^n f''^--n times (1))/(n!)

if f(x) = x^n then the value of f(1) - (f'(1))/(1!) + (f''(1))/(2!) + ---+((-1)^n f''^--n times (1))/(n!)

If 2f(x) +3f(-x)=x^(2)-x+1 then determine the value of f'(1).
