quadratic equations
hi, i need to make this into a quadrattic equation but there is a pert on the table which i can't remember what to do!
when you have x then 3,2,1,0,1,2,3
under that you puy Y and i can remember how to work that out! if you can help i will be very thankful!
my question is Y= x^24x+1 by the way

Replace the values of x in the equation given to you!
For example, under 3, you put:
Hence:

thanks for answering my question! under 2 it would be 11?

Does this equal 11?

no its 13, i think i got it now!! would 1=3?

Think of it again:
Does this make 1?
remember that when you multiply two negative numbers, they become a positive number.

would 0 =1
1=0
2=1
3=1???

for 0: yes.
For 1:
For 2:
For 3:
Hm.. you need to work your basic calculations more...

actually would this be it:
3=19
2=11
1=5
0=1
1=1
2=1
3=1

Are you sure you posted the right equation?

cr@p, no i didn't its 4X sorry!!!!!!!!

I still have no idea what the equation actually is... (Speechless)
