Question

Use a table of values to graph each quadratic function
y= -2*x^2 +2....what are the imputs

Answer 1

try -2,-1,0,1,2

Answer 2

yeah but then after i use those what do i do

Answer 3

get the y values and plot them on a grid

Answer 4

how

Answer 5

You are just graphing. Input is x and output is y

Answer 6

Find the points and connect them.

Answer 7

for example
x y
0 2
1 0
2 -2
the just plot (0,2) (1,0) (2,-2) and so on..

Answer 8

its supposed to be a parabola

Answer 9

that just makes a line

Answer 10

Then What you can do is solve it's zeros by using the quadratic formula. From there you can plot and graph around those values

Answer 11

a=-2 b=0 and c=2

Answer 12

should look like this

Answer 13

Thank you all

Answer 14

hehe you were just a couple of points away from making the parabola. That's why it's always helpful to make a lot of points to get a bigger picture.
