Q: Which of the following is the vertex of the quadratic equation y = 6x2 24x 16?
A: 6x2+24x+16 vertex = (-2 , -8) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 6x2+24x-16 vertex = (-2 , -40) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 6x2-24x+16 vertex = (2 , -8) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 6x2-24x-16 vertex = (2 , -40) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -6x2+24x+16 vertex = (2 , 40) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -6x2+24x-16 vertex = (2

User: Which of the following is the vertex of the quadratic equation y = 6x2 24x 16?

Weegy: An axis of symmetry is the line a parabola forms from the highest or lowest point. First, take -b/2a in this case, -24/4. That is your axis of symmetry. (X=23 is an example of this)

@kikaycore, you can know an answer is not right without knowing the correct answer. You do not need to challenge people, that has become a nasty habit on this site. Now I understand if your answer was right and it was flagged, you should probably speak up. If a lot of correct answers were flagged, then you should send a message to the Weegy Team because they can find out who did the flagging and take care of the problem. This questions has four different possible answers because of the fact that there are no signs (+ or -) between the terms. Also, this was asking for the vertex, not the axis of symmetry. The axis of symmetry in a quadratic equation is the x-component of the vertex and you gave the correct formula for finding the x (-b/2a) but your math is also wrong.
Hold up. Do I sound like I'm challenging someone? haha! I'm just saying if someone knows the answer they can answer it.
