Given that:
Suppose that f is an exponential function with the percentage growth rate of 5%
F(0)=5
By using,
The exponential equation is
F(x)=a(1+r)x
Where a is the initial value and r is the growth rate/decay rate
By using above form of the exponential equation,
Here,
F(0)=5
Then we get
A=5
Growth rate=5%
=0.05
To get,
R=0.05
Plug the values of r=0.05 and a=5 in the above exponential form.
To get,
F(x)=5(1+0.05)x
To get,
F(x)=5(1.05)x
Therefore
F(x)=5(1.05)x
