Question

What is the approximate value of Rs) for the function (*)=6.87(2,5) -$ 294.98fcs) = 6.67ca.=6687ant

Answer 1

To calculate the approximate value of f(5), we have to substitute x=5 on the function f(x):

f(x)=6.87(2.5)^(x-1)

`\begin{gathered} f(x)=6.87(2.5)^(5-1) \\ f(x)=6.87(2.5)^{4^{}} \\ f(x)=6.87((625)/(16)) \\ f(x)=(17175)/(64)=268.36 \end{gathered}`
