I need help answering this question ,

B

Step-by-step explanation: The best way to solve is to use the vertex formula -b/2a to find the x-value of the vertex and then plug that value into the equation to find the y-value, then finding the graph that best suits that vertex. In this case, -b/2a would be -(-2)/ 2(-2) or 2/-4 or -1/2. Since we now know that the x-value of the vertex is -1/2, we know the answer is now narrowed down to A and B. Now, lets plug -1/2 into the equation to find the y.

>-2(-1/2)^2 -2(-1/2) +4

>-2(1/4) +1+4

>-1/2+5

= 4.5

Answer B seems to have the vertex of (-0.5, 4.5)
