(a) Explanation Given: The function of average high temperature is P ( x ) = 0.0376 x 4 − 1.087 x 3 + 8.973 x 2 − 16.326 x + 40.280 . Where, x = 1 corresponds to January and x = 12 represents December. Calculation: The given function of the average high temperature is as follows: P ( x ) = 0.0376 x 4 − 1.087 x 3 + 8.973 x 2 − 16.326 x + 40.280 … … ( 1 ) Since x = 1 corresponds to January and x = 12 represents December, x = 3 and x = 7 stands for March and July respectively. Substitute 3 for x in equation (1) to obtain the average high temp in month of March. P ( x ) = 0.0376 ( 3 ) 4 − 1.087 ( 3 ) 3 + 8.973 ( 3 ) 2 − 16.326 ( 3 ) + 40 (b) To determine The month when the average high temperature is about 80 ° F for the function P ( x ) = 0.0376 x 4 − 1.087 x 3 + 8.973 x 2 − 16.326 x + 40.280 graphically and numerically.
