Exponential

GRAPHS

Logarithmic

INVERSE

NOTES

The inverse of an exponential function is a logarithmic

function.

To convert from an exponential to a log –>

25 = 32 is log2 32 = 5

Calculators only do log10 which is called “common log”

So log is really log base 10.

PROPERTIES OF LOGS-- NOTES

1) logb mn = logb m + logb n

2) logb m = logb m – logb n

n 3) logb mp = p logb m
