The function f(x) = log (x + √(x^2 +1)), is

• Relations Functions

The function f(x) = log (x + √(x² +1)) is

1. an even function
2. an odd function
3. neither an even nor an odd function
4. a periodic function

Solution

f(x) = log(x + √(x² + 1))

f(-x) = -log(x + √(x² + 1))

f(-x) = -f(x)

The correct option is B.
