3.2 -- Logrithmic Functions

Rule to Everything

ex. log(1000) = 3 -----> 1000 = 10^3
Logrithmic Formy = log a (x)

D: (0,∞)
R: (-∞,∞)

Exponential Formx = a^y



Natural Log Functionlog e (x) = ln(x)

D:(-∞,∞)
R:(0,∞)
Ln Vs. Log Graph

1. Ln function is related to the log function, because the are reflected on the line y = x.
