The answer is:
EXPLANATION
I dunno, this is just a technique. I believe you know that the vertex form of a quadratic equation is
Referring to the given vertex, you have (0,6). So, h should be 0 and k should be 6.
You can see that h is absent in the last two equations given that it is only x^2 and not x minus h.
Going to k, we can find that only the third equation has fulfilled a positive k (the fourth has -6).
In problems like this, I think you can already manage that easy to choose which among the quadratic equations show a particular vertex.

Answer:
63.15% upcharge
Step-by-step explanation:
Given:
Principal value = 4580
Rate of interest = 6% apr compounded weekly
To find:
The total amount after 2 years.
Solution:
The formula for amount is
Where, P is principal, r is rate of interest, n is number of times interest compounded in an year and t is number of years.
1 year = 52 week
n=52
Putting P=4580, r=6, n=52, t=2 in the above formula, we get
On further simplification, we get
Therefore, the ending balance after 2 years is 5163.58.
