Give the growth factor $b$, the starting value $a$, the growth rate $r$, and the value of $k$ when $Q$ is written in the form $Q = a \, e^{k\,t}$. If there is exponential decay, then your growth rate should be negative. For help entering logarithms, see help (logarithms)

$Q = 170 \cdot (1.658)^t$ has:
