The # of taxi accidents is approximated by y = -143.3x^2 + 1823.3x + 6820 and the # of injuries is approximated by y = -416.72x^

2 + 4416.7x+ 8500. Let x = 0 represents 1990, x = 1 represents 1991, and so on. According to the equation for the # of accidents, if the trend continued, how many taxi accidents occurred in 1997?

If 1990 is x = 0, then 1997 is x = 7.
Use x = 7 in the equation for the number of taxi accidents.
