The following graph is a translation of the graph of one of the basic functions The equation of the function is defined by y = x" , y= x, y= vx, ory= |x| Find the equation that defines the (Type an equation.) function. Then, determine the largest open interval of the domain over which the function is (a) increasing and (b) decreasing. 6- X -10 -3 -6The table lists the average annual costs (in Year Tuition and Fees (in dollars) dollars) of tuition and fees at public four-year 1993 2614 colleges for selected years. Answer part (a) 1995 2870 through (c). 1997 3185 1999 3349 2001 3844 2003 4679 2005 5398 . . . . . (a) Use a calculator to find the least-squares regression line for these data, where x = 0 corresponds to 1993, x =2 corresponds to 1995, and so on. (Use integers or decimals for any numbers in the expression. Round to one decimal place as needed.)
