Post the equation if you can.

anonymous · Answer

Find the vertex of the parabola by writing in Vertex Form. State whether the vertex is a max or a min. 
f(x) = -3x2 - 6x - 7

Do you know how to convert to vertex form?

anonymous · Answer

not really

anonymous · Answer

im not sure if my answer is right .. ..

jim_thompson5910 · Answer

First move that -7 to the other side. So add 7 to both sides

f(x) = -3x^2 - 6x - 7

f(x)+7 = -3x^2 - 6x


Then factor out -3 from the right side to get


f(x)+7 = -3(x^2 +2x)

Now take half of the x coefficient and square it. What do you get?

anonymous · Answer

-1,-4 maximum
