I have a question on quadratic equation?

Question

I have like no idea how to draw the equation. It goes up and down several times, but I just don't get it.

Answer 1

Heh.  Here's a little trick that will work for these graphs.  If you are TOTALLY screwed up and can't remember any of the rules, all you have to do is plot some test points and you will be able to figure the rest out.

So if you had x^2-6x+9  then you make a table and pick some random x points and solve.  So in this case you would have:

x       y

-2      25

-1      16

0       9

1       4

2        1

3        0

4        1

5        4

6        9

etc

Then when you plot a few points you will see how the graph is.

Good luck.

Answer 2

i can help you..but a dont understand your question

Answer 3

you need to give more detail

we dont know the problem you have

if its an algebra 1 quad eq it should just be a parabula

looks like a U

or upside down U..

give more specifics...

Answer 4

substitute 0 for x and solve for y.  That will get you a y-intercept.  set y equal to zero and solve for x.  you can do this by factoring or using the quadratic formula.  the answer will give you the x intercepts.  then if you need any more points plug in really easy x values such as 1, 2 , etc etc.  It will end up as a U shape.  either pointing up or down.  This is if it is x squared mind you.
