For `f(x)= sqrt(77^x-777^x),D_r` is

Differentiate the following functions w.r.t. x. f(x) = sqrt( 4-x), x lt 4

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

A function f,R rarr R given by f(x)=x+ sqrt(x^(2)) is

Let f:R rarr R be a function defined by f(x)=x+sqrt(x^(2)), then fis

Let f:D rarr R where D is the domain of f then the inverse of f(x)=ln[x+sqrt(1+x^(2))] is

D is domain and R is range of f(x)=sqrt(x-1)+2sqrt(3-x), then

D is domain and R is range of f(x) =sqrt(x-1)+2 sqrt(3-x), then

Consider the function f(x)=sqrt(2-x)+sqrt(1+x) .If 'd' denotes the number of integers in the domain of f and r denotes the number of integers in the range of f , then (d+ r) is equal to
