The number of taxi accidents is approximated
The number of taxi accidents is approximated by y
equals negative 143.3 x squared plus 1823.3 x plus 6820
y=−143.3×2+1823.3x+6820 and the number of injuries is approximated by y equals negative 416.72 x squared plus 4416.7 x plus 8500
y=−416.72×2+4416.7x+8500.
Let x equals
=0 represents 1990, x equals
=1 represents 1991, and so on.
According to the equation for the number of accidents, if the trend continued, how many taxi accidents occurred in 1997
1997?
