Answer
Choice A
Work Step by Step
The graph of the quadratic function, $
f(x)=a(x-h)^2+k
,$ opens downwards when $a<0$. Therefore, the only possible graphs are choices A and C.
The vertex is given by $(h,k)$. With $k<0$, then the vertex is located below the $x$-axis. Between choices A and C, then the most possible graph is Choice A.
