Answer: The axis of symmetry is x= -4
The domain is all real numbers
The function is negative over (“infinite sign”, -4)
Step-by-step explanation:
I’m not sure
Each side after the cut-out is (s-2c) where s is the original side length and c is the size of the cut so:
V=hlw, h=x and l and w are both (x-8)
V=x(x-8)(x-8)
V=x(x^2-16x+64)
V=x^3-16x^2+64x
Is there a picture ? For this problem
