A department store has two locations in a city. From 2012 through 20l6, the profits for each of the store's Iwo branches are modeled by the functions f ( x ) = − 0.44 x + 13.62 and g ( x ) = 0.51 x + 11.14 . In each model, x represents the number of years alter 2012, and f and g represent the profit, in millions of dollars. a . What is the slope of f ? Describe what this means. b . What is the slope of g ? Describe what this means. c . Find f + g , What is the slope of this function? What does this mean?
