Y = f (x) = ln (x + √ (1 + X & # 178;)) x ∈ (negative infinity to positive infinity) inverse function solution detailed explanation, thank you

Note that - y = ln (√ (1 + X & # 178;) - x), | e ^ (- y) = √ (1 + X & # 178;) - x | - e ^ (- y) = x - √ (1 + X & # 178;)
And the exponential function on both sides of the original formula is: e ^ y = x + √ (1 + X & # 178;)
Add two formulas: e ^ y-e ^ (- y) = 2x
The inverse function is y = (e ^ x-e ^ (- x)) / 2
