Final answer:
To find a function that models the given data using logarithmic regression, use the logarithmic regression equation y = a * ln(x) + b. Substitute the values from the data into the equation and find the values of 'a' and 'b'.
Step-by-step explanation:
To find a function that models the given data using logarithmic regression, we can use the logarithmic regression equation y = a * ln(x) + b. Substitute the values from the data into the equation and use a calculator or software to find the values of 'a' and 'b'.
Using the first and last data points, we have:
1.5 = a * ln(1) + b
14.8 = a * ln(5) + b
Using a calculator or software, the values of 'a' and 'b' are approximately 0.5123 and 1.2439 respectively, so the function that models the data is y = 0.5123 * ln(x) + 1.2439.
