Find exponential models
$y_{1} = C e^{k_{1} t}$
and
$y_{2} = C {(2)}^{k_{2} t}$
That pass through the two given points. Compare the values of $k_{1}$ and $k_{2}$ . (If you round your answer, round to four decimal places.)
$(0, 16), (60, \frac{1}{4})$
$y_{1} = C e^{k_{1} t}$ where C=?
and $k_{1} = ?$
$y_{2} = C {(2)}^{k_{2} t}$ where C=?
and $k_{2} = ?$
