माना कि `f: R to R` इस प्रकार परिभाषित है कि `f(x) = x^(2) +1` तो `f^(−1)(26)` =?

If f : R to R is defined by f(x) = x/(x^(2)+1) find f(f(2)) .

If f: R to R is defined by: f(x-1) =x^(2) + 3x+2 , then f(x-2) =

If f:R to R, f(x) =x^(3)+1 , then f is :

If x and y are natural numbers such that x+ y = 2017, then what is the value of (-1)^x + (- 1)^y ? यदि x तथा y प्राकृतिक संख्याएँ इस प्रकार है कि x+y = 2017 है, तो (-1)^x + (- 1)^y का मान क्या है?

If f :R to R is defined by f (x) =(x )/(x ^(2) +1), find f (f(2))

If f :R to R is defined by f (x) =(x )/(x ^(2) +1), find f (f(2))

If f : R to R is continuous such that f(x + y) = f(x) + f(y) x in R , y in R and f(1) = 2 then f(100) =

If f : R to R is defined as f (x+ y) = f (x) + f (y) AA x, y in R and f (1) = 7, then find sum _(r =1) ^(n) f (r).
