Explanation

Use the variable assignments from the quadratic formula to find -b/2a. b= -8 and a = -2. So, -b/2a = 8/-4=-2. The x value is -2.

Now substitute -2 into the original equation. y=-2(-2)^2 - 8(-2) -1 and simplify. Watch your signs. You should get y= -8+16 -1 which is 7. So the answer is A.
