The monthly average high temperatures in degrees Fahrenheit at a beach can be modeled by
P(x)=0.0144 -0.426² +3.5562-6.314x+73, where x=1 corresponds to January and x=12 represents December
(a) Find the average high temperature during May and Jully.
(b) Estimate graphically and numerically the months when the average high temperature is about 80°F.
(a) Using the model P(x), the average high temperature in May is F, and the average high temperature in July is F. (Type an integer
or decimal rounded to the nearest tenth as needed.)
