Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).
Consider the given function.
[tex]\[ f(x) = e^{2x} - 4 \][/tex]
To determine the inverse of the given function, change [tex]\( f(x) \)[/tex] to [tex]\( y \)[/tex], switch [tex]\( x \)[/tex] and [tex]\( y \)[/tex], and solve for [tex]\( y \)[/tex]. The resulting function can be written as:
[tex]\[ f^{-1}(x) = \frac{\ln (x + 4)}{2} \][/tex]
