Answer:
1. Formula is A2 : A9 = COUNT( A2: A9 ) = 8
2. Formula is SUM( A2: A9 ) = 36
3. Formula is B2 : B9 = COUNT( B2: B9) = 8
4. Formula is MAX( C2: C9) = 5
5. Formula is MIN( C4: C8) = 3
6. Formula is SUM( C5 - C6) = 0
7. Formula is AVERAGE( C2: C9) = 4

Answer:
To figure what?
It doesn't show anything?
Answer:
y = x² - 3x - 28
Step-by-step explanation:
given a parabola with x- intercepts x = a and x = b , then
(x - a) and (x - b) are the corresponding factors and the equation is the product of its factors
y = (x - a)(x - b)
here the x- intercepts are x = - 4 and x = 7 , then the factors are
(x - (- 4)) and (x - 7) , that is (x + 4) and (x - 7) , then
y = (x + 4)(x - 7) ← expand using FOIL , then
y = x² - 3x - 28 ← in standard form
