The cumulative number of car accidents from 2000 to 2010 can be modeled by the quadratic expression , C=-26^2 + 676x + 7618 , where x=1 corresponds to 2000, x=2 corresponds to 2001, and so on.
Find the number of cumulative car accidents in 2004 is ?
The number of car accidents reached 9900 in the year?

anonymous · Answer

just replace the x with 5

Ah I see now, thank you

anonymous · Answer

no problem ^^
you know why you have to put in 5?

anonymous · Answer

Yes that is where the varible has to substitute for the equation?

anonymous · Answer

i mean the coherence:
2000, x=1
2001, x=2
...
2004, x=5
that's what i meant ;D

Yes:)
