Answer:
(2,-5)
Step-by-step explanation:
The vertex form is 
and has vertex (h,k). Remember h is the opposite value of the value in the equation.
This means 
has vertex (2,-5)
We will see that there are 156,000 different combinations, so the correct option is C.
<h3>How many possibilities are there? </h3>
First, we need to find the selections, here we have:
- First letter.
- Second letter.
- Third letter.
- Number.
Now we need to find the number of options for each of these selections.
- First letter. (26 options)
- Second letter. (25 options, because we can't repeat letters)
- Third letter. (24 options)
- Number. (10 options).
We assumed that the number can be any integer from 0 to 9.
The total number of possibilities is equal to the product between the numbers of options, we will have:
P = 26*25*24*10 = 156,000
So, the correct option is C.
