Answer 1

The answers are:

1) $x$

2) $x$

3) $\frac{ln(x+4)}{2}$

The explanation for this answer is shown below.

1. To solve this problem you must apply the following proccedure:

2. You have the function $f(x)=e^{2x}-4\\ y=e^{2x}-4$

3. You must switch$x$ and $y$ and then solve for$x$:

$x=e^{2y}-4\\ x+4=e^{2x}\\ ln(x+4)=2y\\ y=\frac{ln(x+4)}{2}$

4. Finally, you obtain:

$f^{-1}(x)=\frac{ln(x+4)}{2}$
