Equation is
(c)
To find: The linear model of graph
(c)

Answer to Problem 18E
The linear model of graph is
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 530,000
(d)

Answer to Problem 18E
The year is 2021. As the linear model is not a good fit so it can`t be estimate.
Explanation of Solution
Given information:
Battery stock will be 530,000
So the year is 2021
As the linear model is not a good fit so it can`t be estimate.
