Let f(x)f(x) be the height of a maple tree in inches and xx the number of years since 2000. A linear model for the data is f(x)=9.44x+84.182f(x)=9.44x+84.182. A) To the nearest inch, estimate the height of the maple tree in 2017.  inches B) Use the equation to find the year in which the tree will be 248 inches tall.

In the given equation , sketch the graph of the function   y = 3- lxl

Find the point on y = x that has a slope of -8.

Interpret the unstandardized coefficient for highest years of schooling. E.g., Is the relationship positive or negative? How does a one-unit change in schooling (i.e. an increase in one-year of education) influence Y?  Interpret the constant (i.e. the intercept) in the equation? What does it indicate? Calculate the average number of hours watched for someone with 12 years of education.
