Question

The monthly average high temperatures in degrees Fahrenheit at a beach can be modeled by P(x) = 0.0143x4 -0.425x3 +3.545x2-6.256x+64, where x = 1 corresponds to January and x = 12 represents December.

(a) Find the average high temperature during March and August.
(b) Estimate graphically and numerically the months when the average high temperature is about 70°F.
(
a) Using the model P(x), the average high temperature in March is F. and the average high temperature in August is °F. (Type an integer or decimal rounded to the nearest tenth as needed.)
