the cumulative number of car accidents from 2000 to 2010 can be modeled by the quadratic expression
C=-30x^2+1140x+9,450,where x=1 corresponds to 2000,x=2 corresponds to 2001,and so on until x=11 corresponds 2010
(a) use a table of car accidents in 2003 is
(b) use a table of value to estimate the year in which the cumulative number of car accidents reached 12,600.
the number of car accidents reached 12,600 in about the year

Question

the cumulative number of car accidents from 2000 to 2010 can be modeled by the quadratic expression
C=-30x^2+1140x+9,450,where x=1 corresponds to 2000,x=2 corresponds to 2001,and so on until x=11 corresponds 2010
(a)  use a table of car accidents in 2003 is
(b) use a table of value to estimate the year in which the cumulative number of car accidents reached 12,600.
the number of car accidents reached 12,600 in about the year
