Answer:
c. 10^2
Step-by-step explanation:
It can be helpful to remember that an exponent signifies repeated multiplication. Here, the denominator factors cancel an equal number of numerator factors
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
