Write the inverse of f(x) = 3^x - 1
NeTakaya

The inverse of this function would be f(x) = \frac{Log(x - 1)}{Log3}.


You can find the value of any inverse function by switching the f(x) and the x value. Then you can solve for the new f(x) value. The end result will be your new inverse function. The step-by-step process is below.


f(x) = 3^{x} - 1 ----> Switch f(x) and x


x = 3^{f(x)} - 1 ----> Add 1 to both sides


x + 1 = 3^{f(x)} -----> Take the logarithm of both sides in order to get the f(x) out of the exponent


Log(x + 1) = f(x)Log3 ----> Now divide both sides by Log3


\frac{Log(x - 1)}{Log3} = f(x) ----> And switch the order for formatting purposes.


f(x) = \frac{Log(x - 1)}{Log3}


And that would be your new inverse function.
