O STATISTICS = Choosing a quadratic model and usin... Sierra V 00/5 The data points show an ocean trench's depth y (in feet) at a distance x from a marked buoy (in feet). Each figure has the same data points. However, each figure has a different curve fitting the data. The equation for each curve is also shown. Answer the questions that follow.
