Technology required. Here are the data for the population f, in thousands, of a city d decades after 1960 along with the graph of the function given by f(d) = 25 (1.19)d. Elena thinks that shifting the graph of f up by 50 will match the data. Han thinks that shifting the graph of f up by 60 and then right by 1 will match the data. population (thousands) 150 125 100 75 50 25 1 2 4 5 time (decades after 1960) a. What functions define Elena's and Han's graphs? Elena's: Han's: 6 :: f (d +50) :: f (d) + 50 :: f (d-1) + 60 :: f (d + 1) + 60
