Algebraic Model: The taxiway ised by an aircraft to exit a runway should not have sharp curves. The table lists the minimum radius y of the exit curves (in feet) for a taxi speed of x miles per hour. Find an algebraic model that fits the data. Include a graph of the model and use the model to find a safe taxi speed for an exit curve with a radius of 500 feet.

x mph 0 10 20 30 40 50

y feet 0 50 200 450 800 1250
