Graphing with vertex form?

doesn't your book, teacher, or fellow classmates have a clue?\nasking such questions here, you will get a lot of crap answers.\nhow will you know what's right?

if you have done the graph yourself, you should use MS paint to copy that to PC, or you might be considered cheating (since most graph program is an "equation-to-graph-auto -converter", thus needing you just to copy the equation the click ok then send, not thinking at all). Using Paint for plotting graph is not easy and is very messy though. But to graph it in Paint, you have to do some maths to calculate where to place the points, and this might lessen the anger of the online teacher if he mind the student use a graph program to do homeworks

Well, if you're using Microsoft Office, Excel provides many chart and graphic options.\nStatistical software also provide those functions, but they're really expensive.\nHere's a link for some software. Some are free, and others are shareware or have free demos that might serve you:\nhttp://dmoz.org/Science/Math/Software/Graphing/

Please calm down. Now do you want the line between (2,0) and (-2,-2) The way I do it is to get the point vector solution of the line and eliminate t. The point is (2,0). The vector is <-2 - 2, -2 -0>. Just subtract the first coordinate from the second. So the vector is <-4, -2> \nNow set up the point vector equation describing the postion of the graph at time t.\nJust point + vector*t in component form.\nThe x-components: x = 2 - 4t \nThe ys: y = 0 - 2t\n\nThere, that is it. But some nasty professors don't like this form, so we'll eliminate t. We plug y = -2t into first equation and get x = 2 + 2y.\n2y = x - 2. y = x/2 -1.

if your equation is y=x^2, then the graph that you draw is going to be a parabola. You can see this by having a table first. The table should consist of 2 values...x and y. So you say when \nx=-3, y=9,\nx=-2, y=4,\nx=-1, y=1\nx=0,  y=0\nx=1,  y=1\nx=2,  y=4\nx=3,  y=9\nso now if you have a square line paper, just plot it and you will see that it will give you a parabola. Another thing is that when you draw it, first just plot the points and then when you connect the point connect them using curves and not a line,...that's why u get a u shaped graph and not just a combo of lines.

you would plot it on a graph at (0,5) \nor "y-int=5"

No U can not make graphs using microsoft word. Instead, U have to use microsoft excel to make graphs. There are other softwares like SPSS, MSTATC, D-Base, SAS, GenSTAT. These softwares are basically used in research database preparation and analysis. So, for simpple kind of graphs from simple database Excel is the best. Thank You.

No, you must use algebra to plot lines. How else would you explain the variables x and y?\n\nSlope-intercept form looks like this:\n\ny = mx+b\n\nOr, in the case of vertical lines:\n\nx = my+b\n\nWhere m is the slope and b is the x- or y- intercept, depending on which one you are using.

Which function, Subsitution, Linear COmbination, Graph?

A graphing calculator has very few pixels, so all the graphing calculator has to do is plug in a finite amount of values into the equation and illuminate a finite amount of pixels. The fast custom processor and memory banks make this seem almost instantaneous.\nSimple home computer software graphs curves by evaluating the equation at some finite amount of points, and connecting those points with lines (or simple polygons for surfaces). Professional software such as Mathematica uses more advanced algorithms to render curves and surfaces.

What are you looking for?\nSlope?\ny=mx+b form?\nI will come back to read additional details.

Do you mean graph? Look in your math book. You take a pencil and you graph ordinarly basically.

y=(x+3)^2=x^2+6x+9\ny'=2x+6=0\n2x=-6\nx=-3\ny(-3+3)^2=0\nso the vertex is (-3,0)

It allways depends on the graph you are drawing, theres no setup, that would match all graphs, that u can make the Ti draw. I mostly use the zoom functions of this Ti, its way faster then to set up the view everytime.

There are many such programs available:\n\n   http://www.google.com/search?q=graphing%20functions%20plot%20save\nhttp://dir.yahoo.com/Business_and_Economy/Business_to_Business/Scientific/Software/Mathematics/Calculators/Titles/\n\nSome are commercial, while others are free such as:\n\nhttp://www.c-lunch.org/~jwozniak/wg/main.html\n\nor the long-standing (and excellent) GnuPlot:\n\nhttp://www.gnuplot.info/\n\nThough GnuPlot is not GUI-based.

you can use Microsoft Spread Sheet or Excell add all the data and it will make you all kinds of graphs

Strange parabola.\n\nBring the form to x = a(y-h)^2 + k\nThe vertex is (h,k).\nThe directrix will be x = k - m\nwhere m = 1/(4a)
