What is the inverse of the function??
Firlakuza [10]
\(\begin{matrix}&#10;y=ln(x+3)\\&#10;e^y=x+3\\&#10;e^y-3=x\\&#10;swap ~x~and~y\\&#10; \huge\underline{y=e^x-3}}&#10; \end{matrix}\)&#10;

To get the inverse of any function f(x) [ just make sure that it passes the horizontal line test] follow the steps:

- Solve for x, i.e separate x in one side and the other terms in the other side, included f(x).

- Swap x and f(x).

- The result is the inverse of the original function f^{-1}(x).

-------------------------

Apply that on your function
\(\begin{matrix}&#10;y=ln(x+3)\\&#10;e^y=x+3\\&#10;e^y-3=x\\&#10;swap ~x~and~y\\&#10; \huge\underline{y=e^x-3}}&#10; \end{matrix}\)&#10;
