Car Performanee The time ; (in seconds) required to attain a spceil of s miles per hour from a standing start for a Dodge Avenaer is shown 111 the table. (Source: Rood S: Truck) (a) Use the regression capabilities of a graphing ulilily to find a quadradc model for the data, (b) Use a graphing utility to plot the data and graph the model. (c) Use the graph in part (b) to state why the model is not appropriate for determining the lime iei.|uired to attain speeds less than 20 miles per hour. (d) Because ihe les( began from a standing start, add the point (0. 0) to the data. Fit a quadratic model to the revised data and graph the new model. Does it more accurately model the beha\ ior of the car for low speeds'' Explain.
