The weight and fuel economy for various vehicles were measured and recorded in the scatterplot to the left. given that w represents the weight of the vehicle, in thousands of pounds (lbs), and f represents the fuel economy, in miles per gallon (mpg), which of the following equations best models the relationship between f and w.

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
