Question: The table gives the wind chill temperature when the outside temperature is 20°F. (a) Use x as the wind speed and create a quadratic model

The table gives the wind chill temperature when the outside temperature is 20°F.

(a) Use x as the wind speed and create a quadratic model for these data.
(b) At what wind speed does the model predict that the wind chill temperature will be lowest?
(c) Do you think the model found in part (a) is valid for x > 60? Explain.
