Which of the following is not a function? O f = {(1,2), (2,4), (3,6), (4,8), (5,10) O h= {(1,1), (1,2), (2,3), (2,4), (3,4)} O k= ((-2,2), (-1,3), (0,4), (1,5), (2,6)} O g = {(-1,3), (0,1), (2,5), (4,8), (8,8)} Working alone at a constant rate, Carla can wash a load dish in 42 minutes, If Carla works together with Dan and they both work at a constant rate, it takes them 28 minutes to wash the same load of dishes. Working at a constant rate, how long would it take Dan to wash the load of dishes by himself?
