Charlie used a regression calculator to generate the equation f(x) = –0.15x + 20.1 for the ordered pairs (2, 15), (4, 21), (6, 26), (8, 20), and (10, 14).

Is a linear representation the best way to represent the data? If it is, explain why. If not, explain why and suggest a better alternative.

Respuesta :

Answer and Step-by-step explanation:

According to the given situation, The r-value associated with the ordered pairs for the linear function is very nearest to zero which does not results in adequate presentation of the outcome.

A quadratic model could properly comprise of a combination of data, as the set of data has a turning point.

This result in data rises and falls which represents the graph of quadratic's graph

A linear representation is not the best way to show the data from the equation as derived from the regression calculator.

What is the linear representation about?

Note that when plotted on a graph, it will show an upside down u kind of shape, and it as such look linear is not a good choice.  

Note also that the r-value is linked with the ordered pairs for the linear function as it is said to be closer to zero and thus, it does not show an adequate depiction of the outcome.

Therefore, A linear representation is not the best way to show the data from the equation as derived from the regression calculator.
