4th degree, so the ends both point in same direction
positive leading coefient so both ends point up
factor it to see wheere the roots are
the roots are r1,r2,r3,r4 in P(x)=(x-r1)(x-r2)(x-r3)(x-r4)
factor
P(x)=(x-3)(x-2)(x+1)(x+3)
the roots are
3,2,-1,-3
disregard negative roots becasue you can't have negative time or something
3 or 2
see my rough graph

7.83% of the racers did not complete the race.
Step-by-step explanation:
Given,
Total racers who started = 230
Racers who completed = 212
Racers who gave up = 14
Disqualified racers = 4
Therefore, those who gave up and disqualified could not complete the race.
Racers who did not complete = 14+4 = 18
Percent of racers =
Percent of racers =
Percent of racers = 7.826%
Rounding off to nearest whole number
Percent of racers = 7.83%
7.83% of the racers did not complete the race.
