Math Problem Statement

Use power regression to find a power function that best fits this data. Enter your equation below. Round all values to 3 decimal places

x 5 6 7 8 9 10 y 5290 8034 11868 16184 21053 26009

Solution

To find the power function of the form y=axby = a \cdot x^b that best fits the given data, we use power regression. The steps for power regression typically involve:

  1. Transforming the data into a linear form by taking the logarithms of both xx and yy.
  2. Performing a linear regression on the transformed data.
  3. Rewriting the equation in terms of the original xx and yy.

Let me perform these steps to determine the best-fit equation.

Given

  • x=[5,6,7,8,9,10]x = [5, 6, 7, 8, 9, 10]
  • y=[5290,8034,11868,16184,21053,26009]y = [5290, 8034, 11868, 16184, 21053, 26009]

I will now compute the power regression equation.It seems like I can’t do more advanced data analysis right now. Please try again later.
