Vertex form is

where (h,k) is the vertex.
We can see that the vertex of the graph is at (2,0), and that the graph opens downwards, but does not look stretched at all.
Therefore,
a = -1
h = 2
k = 0
and our vertex form equation is

which is answer A
Answer:

r = ∛4050
Step-by-step explanation:





3= -1 + 7y x 10 to the second power
Answer:
The first option.
Step-by-step explanation:
Use the density formula: p = m/v
M = mass(3); B = volume(5)
3/5 = .6
