Question

B) If the model is quadratic give an estimate for the vertex C) of the model is linear find an equation for the model. (Let x be the independent variable and Y be the dependent variable if the model is not linear enter Not Linear)

Answer 1

A) In order to create a scatterplot of the data, we use the values on the column "Input" as the horizontal coordinate of each point, and the values on the column "output" as the corresponding vertical coordinate of each point.

So, using the given values, we create the following scatterplot:

B) A quadratic model has a scatterplot that approximates a parabola. That seems to be the case for the scatterplot above, which shows a parabola, for which we can estimate the vertex to be (-2, 10).

C) As we observed in part B, this model seems to be quadratic, not linear.
