The graph of two functions, f and g, is illustrated below. Use the graph to answer parts (a) through f). 10- y G (a) (f+g)(2)= (Simplify your answer.) (b) (f+g)(4)= (Simplify your answer.) (c) (f-g)(6)= (Simplify your answer.) (d) (gf)(6)= (Simplify your answer.) (e) (fg)(2)= (Simplify your answer.) f(x) (21) > (6-1) 10 (f) (2,-1) (4-1) (63) g(x) (4,-5) Ho- (4) = (Simplify your answer.) -10
