Steps to Graph a Parabola:

Step 1: Write the quadratic equation in Standard Form.

Step 2: Determine if the vertex will be a minimum or maximum.

Step 3: Find the vertex.

• Identify the values of “a” and “b”, and use the formula x = negative b over 2 times a to find the

x-coordinate of the vertex.

• Substitute the x-coordinate of the vertex into the quadratic equation and solve for y.

Step 4: Graph the parabola.

• Plot the vertex on the coordinate plane.

• Pick two values for x to the left of the x-coordinate of the vertex and two values to

the right of the x-coordinate of the vertex for your T-chart.

• Substitute each x-coordinate and solve for the corresponding y-coordinate.

• Plot the points and connect them with a parabola.

I've downloaded every browser, internet explorer, google chrome, firefox, safari, all of them have trouble loading the webpage, for example when I go on facebook, the login page is normal, but when I log in the facebook page comes out as if i don't have an adobe flash player installed which I did re install, I took a screen shot of what I'm talking about if it helps, please help! http://prntscr.com/93gm9

I logged in my Facebook account today and it said "For security reasons your account is temporarily locked". I went step by step and put my phone number to receive the code to unlock my account, but it never sent anything and I tried a couple times more and it says "You have requested too many times, please try in a few minutes" And I did and it said the same thing, I already tried resetting with a new password and the same message came up, this is ridiculous I just want my facebook account back, please help!

I just recently got a BlackBerry Curve 9330, The internet service doesn't work, even though i called Verizon they said the service on my phone seems fine, But it only works when I use Wifi, is this just because my phone is new? Or are the BlackBerry servers down? Please help!

I plan on getting my lip pierced very soon, I have a couple of friends that have lip piercings, Im getting the smallest lip piercing size possible. I will need to have the stud out for a small period of time. Ive heared that using Liquid Foundation to cover this piercing may work, But I'm also worried of infections and the fact that this MAY not work, What should I do, and how should I do it?
