Question

Any buddie good with graph quadratic equation: make table of value

Answer 1

make a table

Answer 2

Complete the square and graph, seems reasonable.

Answer 3

\[
\begin{array}{r}
x&|&y \\
\hline
-3&|\\
-2&|\\
-1&|\\
0&|\\
1&|\\
2&|\\
3&|\\
\end{array}
\]

Answer 4

Or use table of values xD

Answer 5

questione explicitly asks to use table ad i also want to know how to make tables in latex ;)

Answer 6

I'm impressed that you made a tables of values using LaTeX haha. I was thinking you would draw it out.

Answer 7

So kathy do you understand the table of values, its just plugging and chugging.

Answer 8

i dont know how to do these is the ting

Answer 9

do you know how to plot a point ?

Answer 10

not for these i cant graph these i suck if it game me points i could do it i cant figure points out i always have promblem

Answer 11

its a one time thing, once you know how to locate a point like `(4, 6)` on xy plane, you will find these easy

Answer 12

i never doooo

Answer 13

You have the equation \[y=x^2+2x-2\]
and if you look at ganeshies table, he gave you a bunch of x - coordinates, remember a graph has points such (x,y).

So what you want to do is, take the x coordinates and plug it in the equation and that will give you the corresponding y - value.

So for example, lets take x=-3

\[y=(-3)^2+2(-3)-2 \] solve for this and you will get the y value, and you can plug it in your graph as the point (x,y).

Answer 14

Hey, they made it easy for you, just need three points :P

Answer 15

but i still dont understand thesse

Answer 16

That's because you're not trying, so what is \[y=(-3)^2+2(-3)-2?\]

Answer 17

its okay lets first see how to locate the point (4, 6) on xy plane

Answer 18

are you good with directions ? East West North and South ?

Answer 19

Oh I have an idea for you if you're just learning to graph

Answer 20

all i know is up is always + down is aways -

Answer 21

thats all you need to know

Answer 22

also right is + and left is -

Answer 23

if it told me to grah (-3,5) i could do it

Answer 24

u read from the right

Answer 25

then you're all good and ready! just create a table and plot the points

Answer 26

i dont know what the points r

Answer 27

Ok so you have the points (x,y) right? x is the horizontal axis (left, right) and y is the vertical axis (up, down) so if I say graph the point (1,2) here is something you can do

Answer 28

its gonna got to the 1 up to

Answer 29

you can draw these lines as I just made, this is a great way to learn, or at least I tell myself that haha.
