SSA / ASS

2 solutions check !


log b of mn =

log b of m + log b of n


log b of m/n =

log b of m  log b of n


inverse of function

substitute y for x or x for y


continuously compounded interest

a = pe ^ rt
p = starting amount r = rate t = time 

scientific

y = ne ^ kt


appreciation / depreciation

V = p(1 +r) ^ n
p = starting amount r = rate of growth / decay n = time
