Following are some of the salient features of the exponential functions:
(1)
Domain of the exponential function is R, the set of all real numbers (2)
Range of the exponential function is the set of all positive real numbers (3)
The point (0, 1) is always on the graph of the exponential function (this is a
restatement of the fact that b0 = 1 for any real b > 1) (4)
Exponential function is ever increasing; i
