Question

graph y>2x^2-4x+1

Answer 1

can u graph y=2x^2-4x+1

Answer 2

all i really need to figure out is what to first do i don't know how to get the x,y yet?

Answer 3

well you can plot points (x,y).

an easy one is when x = 0, y = 2(0) - 4(0) + 1 = 1

so (0,1) is a point

the graph will look something like a U

Answer 4

construct a table of x and y values for your plots

Answer 5

OK so is it (x+0)(x+1)

Answer 6

to start out

Answer 7

no get some graph paper and plot points

Answer 8

ok

Answer 9

eg
x y
-- --
1 -1 (2(1)^2 - 4(1) + 1}

-1 7 (2(-1)^2 - 4(-1) + 1)

plot another few points

Answer 10

i got it

Answer 11

it will look like this link

Answer 12

you can also find the zeros of the function

by solving 2x^2 - 4x + 1 = 0

Answer 13

i don't know what algebra level you are at
can you do the above operation?

Answer 14

OK thanks
