The relation represents a growth when b>1 and a decay when 0<b<1
Step-by-step explanation:
Any function in the form , where a > 0, b > 0 and b not equal to 1 is called an exponential function with base b. If 0 < b < 1. It is an example of an exponential decay. The general shape of an exponential with b > 1 is an example of exponential growth. An exponential function is expressed in the form The relation represents a growth when b >1 and a decay when 0<b<1.
