Vikentia [17]

Answer:

  A) The model exists: f(x) = -3x^2 +4x -4

Step-by-step explanation:

Here, the slope between -1 and 0 is positive, and the slope between 0 and 3 is negative. Thus, we know these points are not collinear, and a model must exist.

The model is most easily found using a quadratic regression tool. Such is shown in the attachment. It tells us that ...

  f(x) = -3x^2 +4x -4
