| l i The table gives the wind chill temperature when the outside temperature is 15F a. Use x as the windspeed and create a quadratic model for the data. b. At what wind speed does the model estimate that the wind chill will be 7F? C. Is the model found in part (a) valid for .= x> 66? Explain. Wind Wind Wind ' Chill (F) Chill (F) mm 15 0 mm . lm 25 '4 -\"m a. Determine the quadratic function that best ts the given data. y = (Use integers or decimals for any numbers in the expression. Round to the nearest thousandth as needed.) b. Using the unrounded quadratic model from part (a), at what wind speed does the model estimate that the wind chill will be 7F? D mph (Round to the nearest whole number as needed.) 1:. is the model found in part (a) valid for x > 66? Explain. Choose the correct answer below. 0 A. No. The function's minimum is near 65.1 so the model predicts warmer temperatures for winds over 66 mph. B. Yes. The function increases forx> 66 and this reflects reality. 0 C. No. The model is not a good t
