1. Problem Description

The problem asks to find the inverse of the function f(x)=log3(x+2)f(x) = \log_3(x+2).

2. Solution Steps

To find the inverse of the function f(x)=log3(x+2)f(x) = \log_3(x+2), we first replace f(x)f(x) with yy:
y=log3(x+2)y = \log_3(x+2).
Then, we switch xx and yy:
x=log3(y+2)x = \log_3(y+2).
Next, we solve for yy. We rewrite the equation in exponential form:
3x=y+23^x = y+2.
Finally, we isolate yy by subtracting 2 from both sides:
y=3x2y = 3^x - 2.
Therefore, the inverse function is f1(x)=3x2f^{-1}(x) = 3^x - 2.

3. Final Answer

f1(x)=3x2f^{-1}(x) = 3^x - 2
