These data can be modelled by a logarithmic regression function of the form yzalb-lnm Determine a logarithmic regression function that best fits these data. Round the values of a and b to the nearest tenth. F According to the logarithmic regression function, determine the y for a: = 112. Round to one decimal place. '9': A new disease begins to spread. When it is first observed, there are 121 active cases. The table shows the number of cases of the disease, 3;, as a function of the number of weeks since the disease began to spread, at. m 3; mm, _ Use your calculator to create a scatter plot from this table. Which scatter plot below best matches the data? Based on the way that diseases spread, we expect that an exponential curve will be the best fit to these data. Use the Epreg function on your calculator to write the number of cases after a: months as a function of :8. Round all values to three decimal places. X y: A scientist studying bacteria in a petri dish begins with a sample of six bacteria. Thereafter, the number of bacteria doubles every hour. Fill in the table below so that :6 represents the number of hours that have passed, and 3; represents the number of bacteria in the petri dish. a: 19' (number of hours) (number of bacteria) - Part2 of 5 Use the information given above or the Epreg function on your calculator to write 3; as a function of 3:. Round the starting value and multiplier to the nearest integer, if necessary. X y
