The bar graph shows the number of fatal vehicle crashes per 100 million miles driven for drivers of various age groups.  For&#8203; example, 25-year-old drivers are involved in 4.1 fatal crashes per 100 million miles driven.&#8203; Thus, when a group of&#8203; 25-year-old Americans have driven a total of 100 million&#8203; miles, approximately 4 have been in accidents in which someone died.  The number of fatal vehicle crashes per 100 million&#8203; miles, f (x) for drivers of age x can be modeled by the following quadratic function.\r<BR>\n" );
