I posted this 2wice and this is the third i didint get any replies yet not even the hate mail. please answer the math problem
How do i find the vertex of this equation.?
i need help with this question could you please show me how to find the vertex of an equation please show step by step.
i am not cheating i want to know this because everytime ask my teacher she ignores me and goes eats cottage cheese.
here is the example. y= (x+3)^2 -1

I haven't done equations like this one in years, but I did find a website that tells you what to do, step by step using a similar problem. Hope it helps.
Some don't answer when a question takes any chunk of time to answer and explain. It is sad to see a teacher not willing to help you, though.
Scroll down to where he states the problem:
Find the vertex of y = 3x2 + 2x – 1
Use the steps he's listed on the left side.
Purple math seems like a nice website to learn from. Link below.

I even checked Mathematica, their answer:
Integrals That Can and Cannot Be Done
Evaluating integrals is much more difficult than evaluating derivatives. For derivatives, there is a systematic procedure based on the chain rule that effectively allows any derivative to be worked out. But for integrals, there is no such systematic procedure.
One of the main problems is that it is difficult to know what kinds of functions will be needed to evaluate a particular integral. When you work out a derivative, you always end up with functions that are of the same kind or simpler than the ones you started with. But when you work out integrals, you often end up needing to use functions that are much more complicated than the ones you started with.
This integral can be evaluated using the same kind of functions that appeared in the input.
In[1]:= Integrate[Log[x]^2, x]
Out[1]= 2 x - 2x Log [x] + x Log [x]sq'd
Humm?

I don't know if this is right, as it has been a while since I tackled this type of problem. But your equation can be simplified down to y=(x+2)(x+4), which means that your two vertex are (-2,0) and (-4,0)...
As I said, I'm not sure! Good luck.

Sorry you feel ignored and I would gladly answer your question if I knew how. I don't believe the people on here (at least not most of the) are ignoring you. Maybe they, like me , just don't know the answer. One thing you can do is go to your couselor. She can at least get your teacher to give you some help.

I found a site that explains this very well. Please click on the link as it has several pages of explanation.
I do not have the math knowledge to personally make sense of this, but perhaps with this help you can understand it better.
If this problem came from a textbook, you can get help at http://hotmath.com/.

Can't help you as I'm an English teacher, not a math teacher, but sorry that everyone is ignoring you :-)

*= times (multiply)
y=(x+3)*2-1
y=(x+3)*1
y=1x+3

x^2+6x+9-1
x^2+6x+8
(x+2)(x+4)
x=-2,-4
