Im pretty sure its 1 but I might be wrong if i did the math wrong
The correct answer would be : -2/5
I hope that this helps you !

Something funny is that the x value of the vertex lies directl in the middle of the x intercepts
so
we see the x intercepts or 0's at x=8 and 2
the average is x=5
so find f(5) to find the y value of the vertex
f(5)=(5-8)(5-2)
f(5)=(-3)(3)
f(5)=-9
vertex is at (5,-9)
the actual way the teacher wants is to expand then compltete the square to get into the form f(x)=a(x-h)^2+k where the vertex is (h,k)
but whatever
verrtex is at (5,-9)
Answer:
The product will always be less than the factor.
Step-by-step explanation:
When you multiply numbers less than 1, you get a smaller factor each time.
