Which function's graph has a vertex at (,)and contains the point (,)?
use vertex formula where and are coordinates of the vertex
A.
...-> and ; so, this function has a vertex at (,)
now check the point (,)

-> since true, this is your answer

no need to check other options
B.
-> not answer
C. -> not answer
D. -> not answer
