There are 120 different possible groups.
(10 * 9 * 8)/(3 * 2 * 1) + 120
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
I believe it's 8 because it's scale is 4 times bigger.
2×4=8
Hm, D would equal either 5 or 6.
Answer:
D) e
Step-by-step explanation:
ln e^e
We know that ln x^a is the same as a ln x
e ln (e)
we know that ln e =1
e (1)
e
