Answer:
The most tickets were written on Saturday .On Saturday 325 tickets were issued
Step-by-step explanation:
The average number of traffic tickets issued in a city on any given day Sunday-Saturday can be approximated by
![T(x) = -6x^2 + 84x + 37](https://tex.z-dn.net/?f=T%28x%29%20%3D%20-6x%5E2%20%2B%2084x%20%2B%2037)
Where x represents the number of days after Sunday
T(x) represents the number of traffic tickets issued.
Sunday = x=0
Monday = x=1
Tuesday = x=2
Wednesday = x=3
Thursday = x =4
Friday = x=5
Saturday = x=6
Substitute x= 0
![T(x) = -6x^2 + 84x + 37\\T(x) = -6(0)^2 + 84(0) + 37\\T(x)=37](https://tex.z-dn.net/?f=T%28x%29%20%3D%20-6x%5E2%20%2B%2084x%20%2B%2037%5C%5CT%28x%29%20%3D%20-6%280%29%5E2%20%2B%2084%280%29%20%2B%2037%5C%5CT%28x%29%3D37)
On Sunday 37 tickets were issued
Substitute x= 1
![T(x) = -6x^2 + 84x + 37\\T(x) = -6(1)^2 + 84(1) + 37\\T(x)=115](https://tex.z-dn.net/?f=T%28x%29%20%3D%20-6x%5E2%20%2B%2084x%20%2B%2037%5C%5CT%28x%29%20%3D%20-6%281%29%5E2%20%2B%2084%281%29%20%2B%2037%5C%5CT%28x%29%3D115)

![T(x) = -6x^2 + 84x + 37\\T(x) = -6(2)^2 + 84(2) + 37\\T(x)=181](https://tex.z-dn.net/?f=T%28x%29%20%3D%20-6x%5E2%20%2B%2084x%20%2B%2037%5C%5CT%28x%29%20%3D%20-6%282%29%5E2%20%2B%2084%282%29%20%2B%2037%5C%5CT%28x%29%3D181)
On Tuesday 181 tickets were issued
Substitute x= 3
![T(x) = -6x^2 + 84x + 37\\T(x) = -6(3)^2 + 84(3) + 37\\T(x)=235](https://tex.z-dn.net/?f=T%28x%29%20%3D%20-6x%5E2%20%2B%2084x%20%2B%2037%5C%5CT%28x%29%20%3D%20-6%283%29%5E2%20%2B%2084%283%29%20%2B%2037%5C%5CT%28x%29%3D235)
On Wednesday 235 tickets were issued
Substitute x= 4
![T(x) = -6x^2 + 84x + 37\\T(x) = -6(4)^2 + 84(4) + 37\\T(x)=277](https://tex.z-dn.net/?f=T%28x%29%20%3D%20-6x%5E2%20%2B%2084x%20%2B%2037%5C%5CT%28x%29%20%3D%20-6%284%29%5E2%20%2B%2084%284%29%20%2B%2037%5C%5CT%28x%29%3D277)
