graphing quadratics

[hollow elbow]

got a test tomorrow been studying the whole weekend stuck on a couple things that i either forgot or dont know how to do. on the single question right now.

1. Do not ping the Moderators, unless someone is breaking the rules.
2. Do not ping the Helper Moderators, unless there is a conflict between helpers.
3. Do not ping other members randomly for help.
4. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
5. Wait patiently for a helper to come along.
6. If the Helper has answered your question, remember to thank them with the Mathematics Ranks bot and close the thread with:

So what do you know about graphing quadratics

[hollow elbow]

ik the basics

like i can graph a normal equation

[odd oak]

So what's the problem with fraction can you tell me what you did till now?

[hollow elbow]

so all i put down was the vertex since thats what it asked i didnt put any points

yet

i should put down the vertex

[odd oak]

Okay let's start with finding the vertex

[regal grove]

What do you mean a "normal" equation?

Sorry.

[hollow elbow]

one without fractions.

[regal grove]

A fraction is just a number.

[odd oak]

@hollow elbow can you find the roots of this eq?

[hollow elbow]

what does it tell me.

[hollow elbow]

you mean determine what they are?

[regal grove]

Are you suggesting that if it was just a 3 instead of a 3/4, you'd know exactly what to do?

[regal grove]

There aren't any.

Not real ones.

[odd oak]

I am teaching him the process he doesn't know if roots exist

[hollow elbow]

we dont have roots?

[odd oak]

No it will always be positive it can't be 0

[hollow elbow]

yeah

oh

ur talking about that

[odd oak]

And always greate than or equal to 6 too

[hollow elbow]

what do i plugin for x

[odd oak]

So we know no roots what does that tell us abt graph?

[hollow elbow]

to find the axis of symmetry and x intercept

[odd oak]

.

[hollow elbow]

dumb it down for me

[odd oak]

Back in a min gotta do smthing

Since it has no roots it will never ne zero hence won't touch x axis right?

@hollow elbow

[hollow elbow]

ik that cause of the vertex

also i think i got it wait

[odd oak]

What will be the vertex?

[hollow elbow]

i put it down where the vertex answer should go

the vertex is always those 2 numbers in equations like that

[odd oak]

For more accurate you can find y at x=0

[hollow elbow]

wdym

[odd oak]

You found the vertex right?

[hollow elbow]

yeah

[odd oak]

Now find when the graph touches y axis by setting x=0

For more accurate

Just the vertex works too

[hollow elbow]

got it.

[odd oak]

You can +close if you are done

[hollow elbow]

+close
