Question

Determine the graph of the quadratic equation y = 8x2 – 8

Answer 1

Do u want me to teach it ?lol

Answer 2

Hm. So it looks like this should be \(y=8x^2 - 8\) yes?

Answer 3

Omg. I wish you would like, go to someone elses question.

Answer 4

I guess just plot points. start -2,-1,0,1,2 And double check on google by copying pasting the 8x^2-8

Answer 5

-2,-1,0,1,2 plug those in the x

Answer 6

@timo86m Once again, with the answer?

Answer 7

He didn't give me the answer?

Answer 8

I explained how to graph.

Answer 9

I already knew it when he explained.

Answer 10

Oh, true enough. I thought this was a question of finding zeros and I saw you list the numbers. Carry on.

Answer 11

This is what happens when I try to read quickly.

Answer 12

@Makayla43 Kindly avoid telling me what to do, please. :)

Answer 13

@timo86m @KNicksfan4life either of you may continue with tutoring, if you like.

Answer 14

@farmdawgnation When did I tell you what to do?

Answer 15

"Omg. I wish you would like, go to someone elses question." It seemed to me you were telling me to leave?

Answer 16

No? I said I wished you would. Telling you what to do would mean me saying "Go" or something.

Answer 17

i think farmdawgnation really likes u makayla43

Answer 18

Matt, Matt, Matt.

Answer 19

I'm in a patient mood. Carry on with tutoring the concept, please.

Answer 20

I'm not understanding what you mean @timo86m

Answer 21

Lol wow.

Answer 22

Ooo, @shadowfiend is kindaa cutee. :p

Answer 23

'Preciate it. Do try to stay on topic please.

Answer 24

Your Welcome, sir. (:

Answer 25

So the most straightforward thing is to remember how multiplying a number into a quadratic changes its plot and how adding to it changes it.

Answer 26

That's the most repeatable way. The easiest is to just plug in some points, always.

So, we can start by plugging in -2, -1, 0, 1, and 2 for x. Try that and see what results you get for y. Then we'll see about plotting them.

Answer 27

I turned it in already. :/

Answer 28

Ah, alas, alas. I hadn't seen the question was closed. I'll let the others take over from here then :)

Answer 29

Okie Dokie. (:

Answer 30

If I have any serious questions, I will ask you, (;
