यदि `f: R to R` इस प्रकार परिभाषित है कि `f(x) = x^2`, तो ` f^(-1)(25)`

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->R is defined by f(x)=x^2 , write f^(-1)(25) .

If f: R->R is defined by f(x)=x^2 , write f^(-1)(25) .

If f: R->R is defined by f(x)=x^2 , write f^(-1)(25) .

If the function f: R to R is defined by f(x)=x^(2)-6x-14 , then f^(-1)(2) is equal to -

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