Answer
$2.1*0.9048^x$, which is in the required form of the function.
$A=2.1$ and $b=0.9048$
Work Step by Step
We can convert the general function of:
$f(x)=c*e^{d*x}$ as: $f(x)=f*g^x$
In the exercise, we have:
$f(x)=2.1*e^{-0.1x}=2.1*(e^{-0.1})^x$
Which gives us:
$2.1*0.9048^x$, which is in the required form of the function.
$A=2.1$ and $b=0.9048$
