Boiling Temperature The table shows the temperatures \(T\left({ }^{\circ} \mathrm{F}\right)\) at which water boils at selected pressures p (pounds per square inch). (Source: Standard Handbook for Mechanical Engineers)

     

       

(a) Use the regression capabilities of a graphing utility to find a cubic model for the data.

(b) Use a graphing utility to plot the data and graph the model.

(c) Use the graph to estimate the pressure required for the boiling point of water to exceed \(300^{\circ} \mathrm{F}\).

(d) Explain why the model would not be accurate for pressures exceeding 100 pounds per square inch.
