फलन `f : R to R` इस प्रकार परिभाषित है कि `f(x)=x^(2)+1` हो, तो `f^(-1)(26)` का मान होगा|

यदि x^(2)+2=0 हो तो x का मान होगा-

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 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 is defined by f(x)=(x^(2)-4)/(x^(2)+1) , then f(x) is

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