Question

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

anonymous · Answer

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

anonymous · Answer

yeah but then after i use those what do i do

anonymous · Answer

get the y values and plot them on a grid

anonymous · Answer

how

anonymous · Answer

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

anonymous · Answer

Find the points and connect them.

anonymous · Answer

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

anonymous · Answer

its supposed to be a parabola

anonymous · Answer

that just makes a line

anonymous · Answer

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

anonymous · Answer

a=-2 b=0 and c=2

Thank you all

anonymous · Answer

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.
