If `f(x)=sqrt(4-x^2)+sqrt(x^2-1)` , then the maximum value of `(f(x))^2` is ____________

f(x)=sqrt(x-4-2sqrt(x-5))

If f(x)=sqrt(2x^(2)-6x+5)+sqrt(2x^(2)-40x+218) ,then the minimum value of f(x) is

If f(x)=sqrt(1-sqrt(1-x^(2))) then at x=0

f(x)=sqrt(x^(2)-x+1)

" If "f(x)=(sqrt(4-x^(2))-3)^(2)+(sqrt(4-x^(2))+1)^(3)" ,then the maximum value of "f(x)" is "N" then "(N)/(7)=

If f(x)=sqrt(x+2sqrt(x))," then "f'(1)=

If f(x)=sqrt(4-x^(2))+(1)/(sqrt((|sin x|)-sin x)) then the domain of f(x) is

If f(x)=sqrt(2x-3)+sqrt(7-3x) ,then the value of f'(2) is?
