Answer:
B
Step-by-step explanation:
Since the y coordinate of the vertex is -4, it has to be the rest of the equation subtracted by 4, which eliminates A and C.
Adding 5 puts it on the left side, so you have to subtract 5.
Then you add all the default info and the info we found out.
y = 2(x-5)^2-4
So technically by process of elimination, B must be the answer.
