If x is the return on U. S. stocks (%) and y is the return on overseas stocks (%) in the same year, the least-squares regression line for predicting y from x is y = -2.7 + 0.47x. You think U. S. stocks will have a return of 10% in 1999. Using this regression line, you predict that the return on overseas stocks will be (a) 7.4% (b) -2.23% (c) 2% (d) 3.17% (e) 27%

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.
