Using exponential function concepts, it is found that the second function has a greater rate, as 0.8 > 0.2.
It is modeled by:
[tex]y = ab^x[/tex]
In which:
Function 1 is given by:
[tex]y = 2(0.2)^x[/tex]
Hence the rate is b = 0.2.
Considering the values on the table, function 2 is given by:
[tex]y = (0.8)^x[/tex]
Hence the rate is b = 0.8.
Hence, the second function has a greater rate, as 0.8 > 0.2.
