logs and exponential functions

The log function is shown below: where b is any number such that b > 0, b≠ 1, and x > 0. b represents the base The function is read "log base b of x". y represents the exponent. Exponential functions are functions that are reflected below:  f (x) = ex   f (x) = 2x   f (x) = (1/2)x  Exponential and logarithmic functions are inverses. The inverses may be revealed by the reflection across y=x.
