Definition 
.
The logarithmic function with base a,
f(x) = logax ,
is the inverse of the exponential function with base a,
g(x) = ax .

Reminder. The graph of an inverse function can be obtained by reflecting the graph of the original function in the line
y = x .

Graph of f(x) = log a x
and g(x) = ax , 0 < a < 1
Graph of f(x) = log a x
and g(x) = ax , a > 1
 
 
a =    
a =
