Which quadratic function best fits this data?

x y
1 250
2 289
3 316
4 335
5 320
6 290

y=−9.16x2+73.04x+183.3

y=9.16x2−73.04x+183.3

y=9.16x2+73.04x+183.3

y=−9.16x2−73.04x+183.3

answer:

i don't understand this, me understand more if you can!

answer: i can’t tell you that

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
