Well, looking at the expression, it has a -5 on the leading term, that means is not just a quadratic, but is a parabolic graph and because the coefficient of the leading term is negative, is upside-down, or opening downwards.
because it opens downwards, it looks like an arc, comes from the bottom up up up gets to a "maximum" or U-turn (vertex), then goes back down down down. So, where's the vertex anyway?

so, that's where the vertex is, and the maximum value for f(x), is the y-coordinate of course, or 9.

Step-by-step explanation:
This can be written as;

Perform factorization
9-a²=difference of squares formula
(3+a)(3-a)
4a²-4a-24
4(a²-a-6)
4(a²-3a+2a-6)
4(a(a-3)+2(a-3))
4((a+2)(a-3))
a²-6a+9
a²-3a-3a+9
a(a-3)-3(a-3)
(a-3)(a-3)
Rewrite the operation as;

Answer:
The volume of each of the smaller boxes = 18.694 inches³
Step-by-step explanation:
The volume of Shipping container = 448.656 inches³
The shipping container hold small boxes of numbers = 24
So, The volume of each of small boxes =
inches³
Or, The volume of each of small boxes = 18.694 inches³
Hence The volume of each of 24 small containers is 18.694 inches³ Answer
