Question

(Image attached) As the years go by, what does the model predict sales will be?

Answer 1

Given:

The model is:

`S(t)=(20t^2+800t+300)/(8t^2+10t+100)`

Find-:

The sketch of the model that predicts the sales

Explanation-:

The function is:

`S(t)=(20t^2+800t+300)/(8t^2+10t+100)`

At zero the sale is:

`\begin{gathered} S(0)=(20(0)^2+800(0)+300)/(8(0)^2+10(0)+100) \\ \\ S(0)=(300)/(100) \\ \\ S(0)=3 \end{gathered}`

The graph is:
