Answer:
Growth when: b>1.
Decay when: 0<b<1.
Step-by-step explanation:
Any function in the form [tex]f(x)=a{\times}b^x[/tex] , where a > 0, b > 0 and b not equal to [tex]1[/tex] is called an exponential function with base b.
If 0 < b < 1 this is an example of an exponential decay.
The general shape of an exponential with b > 1 is an example of exponential growth.
Hence,
An exponential function is expressed in the form [tex]f(x)=a{\times}b^x[/tex], The relation represents a growth when b >1 and a decay when 0<b<1.
