Let `f(x)=log_(2)(x+sqrt(x^(2)+1)).` If `f(a)=b,` then `f(-a)` is equal to

Let f(x) = sin(log_(3)(x+sqrt(x^(2)+1))), x in R , then

Let f(x)=log(x+sqrt(x^(2)+1)), then f'(x) equals.

If f'(x)=(1)/(-x+sqrt(x^(2)+1)) and f(0)=(1+sqrt(2))/(2) then f(1) is equal to -log(sqrt(2)+1)( b )11+sqrt(2)(d) none of these

If f'(x)=(1)/(-x+sqrt(x^(2)+1)) and f(0)=-(1+sqrt(2))/(2) then f(1) is equal to a) -log(sqrt(2)+1) b)1 c) 1+sqrt(2) d) 1/2log(1+sqrt(2))

Let f(x) = log (1-x) +sqrt(x^(2)-1). Then dom (f )=?

If f'(x)=sqrt(x) and f(1)=2 then f(x) is equal to

If f'(x)=sqrt(x) and f(1)=2 then f(x) is equal to
