Explanation of Solution
Given information:
Graph of the year v/s stocks.
By graphing utility the linear model of graph is
(d)
To estimate: The year in which battery stock will be 47,000
(d)

Answer to Problem 19E
The year is 2018. As the linear model is a good fit so it can be estimated.
Explanation of Solution
Given information:
Battery stock will be 47,000
Calculation:
2012 + 6 = 2018
So the year is 2018
As the linear model is a good fit so it can be estimate.
