Question

PLEASE HELP!!!! How do i turn: f(x)=28.65e^(-64x)
into a logarithmic function???

Answer 1

this one?

Answer 2

\[y = 28.65 e^{-64x}\]
ln it all
\[ln(y) = ln(28.65 e^{-64x})\]
\[ln(y) = ln(28.65)+ln(e^{-64x})\]
\[ln(y) = ln(28.65)-64x\]
\[ln(y) -ln(28.65)=-64x\]
\[ln(\frac{y}{28.65})=-64x\]
\[-\frac{1}{64}ln(\frac{y}{28.65})=x\]
is the only thing I can think of for it
