Question

We are given y = ln(x+1). Find x in terms of y

• A. e^y - 1
• B. e^y + 1
• C. e^y
• D. None of these.

Answer 1

The correct option is A

e^y - 1

y = ln (x+1)

Here, we have to express x as a function of y.

We know this property of logarithm -

If $lo{g}_b$ a = c

then a = $b^c$

So, $e^y$ = x +1

Or x = $e^y$ - 1
