A department store has two locations in a city. From \( 2008 \) through \( 2012 \) , the profits for each of the store's two branches are modeled by the functions \( f ( x ) = - 0.33 x + 14.83 \) 

\( g ( x ) = 0.38 x + 10.06 \) . In each model, \( x \) represents the number of years after \( 2008 \) , 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? 

 

Answer

(f+g)(x) = 0.05x+24.89
