You look at the vertex. Are you at the calculus level or the algebra level?

see the sign of x^2 coeffecient

Algrebra II, year three in high school. It's the same as the vertex?

its the opposite actually.
if x^2 coefficient is -ve, its max
if x^2 coefficient is +ve, its min

|dw:1349465625929:dw|

so we have minimum value there

So how do you find the value of it?

max/min value = f(-b/2a)

actually it comes from the formula for vertex,
vertex = (-b/2a, f(-b/2a))

for parabola
f(x)= a x^2 + b x +c
the x coordinate of the vertex is -b/(2a)

Um, like this? |dw:1349465829395:dw|

Given
\[ax^2+bx+c=a(x-h)^2+k\]
The vertex is located at (h, k).

|dw:1349465949629:dw|

that gives the x-coordinate only, y-coordinate gives the max/min value.

coordinate is just a number i think

So how do I find the y-coordinate?

since you got, x-coordinate of vertex = -b/2a = 5

put that x value = 5, in the quadratic, it gives u y-coordinate of vertex

I got it! Thanks guys \(\Large\ddot\smile\)

glad to hear friend :)

hopefully you got y=0
so the vertex is at (5,0)
and the min value is 0

and hw do i get that

smiley..

Yep, I got 0.
the smiley is \large\ddot\smile
:P

ah latex is beautifyul :)

Yes it is :D

Hehe \(\huge\ddot\smile\)

yeah , kymber also taught me to draw heart ♥
\(\huge \color{red}{♥}\)

Nice!

\(\Huge\color{pink}{❥}\) Sideways!

i thought only AccessDenied is the latex guru... we have so many experts over here hmm :)

but thats cheating... thats not latex, u using unicode i guess

Lol yeah.. it's not a \(\LaTeX\) command. Just alt codes :|

still its cool :)

:D

this one :

see if u can get this here...

\(\Huge{⚔}\)

Lol.

i see a box, what u see at ur end hmm

:| I see the swords..

i see box also

What browser are you guys using?

chrome O.o

chrome too

I'm using Mozilla :P

firefox ?

letme login through mozilla

Yeah. I switched to Chrome and it's a box. Use Mozilla! :P

mozilla wins !

what kind of black magic is this!

Firefox is simply superior . .
