K The monthly average high temperatures in degrees Fahrenheit at a beach can be modeled by P(x) = 0.0146x4 -0.428x +3.523x - 6.233x+68, where x = 1 corresponds to January and x = 12 represents December. (a) Find the average high temperature during February and July. (b) Estimate graphically and numerically the months when the average high temperature is about 80F. (a) Using the model P(x), the average high temperature in February is tenth as needed.) CO F, and the average high temperature in July is F.
