the cumulative number of car accidents from 20002010 can be modeled by the quadratic expression, C=33x^2+792x+8,877, where x=1corresponds to 2000, x=2 corresponds to 2001, and so on untill x=11 corresponds to 2010
a)find the number of cumulative car accidents in 2005?
b)use the table of variables to estimate the year in which the cumulative number of accidents reached 10,33

plug in x=6
solve for x when C=10,33 (?)
