Respuesta :

Answer:

Function B, because the points have more variation around the x-axis.

Step-by-step explanation:

Remember that if the points in a residual plot are randomly dispersed around the horizontal axis, a regression model is appropriate for the data. Therefore, the function that is the best fit for the data is function B, because the points have more variation around the x-axis.
