Lead was banned as an ingredient in most paints in 1973, although it is still used in specialty paints. Lead usage in paints from 1940 through 1980 is reported in the table. Lead Usage ' Faint -_ Year (thousand tons) 1980 (a) Compare the t ofa quadratic model and an exponential model for lead usage. which model ts the data better? O exponential model Q quadratic model \\' (b) Align the data so thatx = 0 in 1935. Compare the t ofa quadratic and a log model for lead usage. which model ts the data better?| O logarithmic model Q quadratic model X (c) Because lead usage in paint was generally banned in 1978, which model best fits the end behavior? O exponential model C logarithmic model quadratic model X (d) Write the Function for the quadratic model that gives lead paint usage in thousand tons, whereX is the number of years after 1935, with data from 5 S x S 45. (Round all numerical values to three decimal places) u[X) = X
