For the data in Exercise 50, find equations for the quadratic, logarithmic, and power regression models. Which of these three models fits the data the least well?

Data from Exercises 50

Find the indicated regression models. Sketch the curve and data points on the same graph.

In an elementary experiment that measured the wavelength L of sound as a function of the frequency f, the following results were obtained.

Find the equation of the exponential regression model for these data that expresses L as a function of f.
