Question

Do not understand or now what the question is asking?

Answer 1

We were given the expression:

`f(x)=-4(2)^(x-1)`

We will obtain the recursive from this:

`\begin{gathered} f(x)=-4(2)^(x-1) \\ \text{The recursive form is given by:} \\ a_n=r\cdot a_(n-1) \\ \Rightarrow a_1=-4 \\ a_n=2a_(n-1) \end{gathered}`
