f(x) is differentiable function sattisfying the relationship f^2(x) + f^2 (y) + 2(xy - 1) = f^(2) (x + y) AA x, y in R . Also f(x)gt 0 A x in R, and f(sqrt2) = 2 . Then which of the following statements is//are correct about f(x)?

Answer»

`[f(3) = 3([.] "is GIF")`
`f(SQRT(7)) = 3`
`f(X)` is even
`f'(0) = 0`
