math question help

Answer 1

shoot

Answer 2

is the line up or down for graphing
y = –2x² + 2

Answer 3

1) this is a quadratic and cannot be a "line". It is a "curve"

Answer 4

thats what i mean sorry is the curve up or down

Answer 5

2) we then check the coefficient of the highest power of "x"

Answer 6

i put it as down but im not sure

Answer 7

it will first increase from -infinity, then reach a maximum and then decrease

Answer 8

okay i get that

Answer 9

so does it look like this then

Answer 10

sorry i couldn't draw it

Answer 11

looks like this. I cannot see your picture.

Answer 12

oh sorry it was a pic that looked like the one you drew except the curve was under the x axis is that correct?

Answer 13

yep. So, it first increases and then decreases.
did you study derivatives?

Answer 14

yes and thank you :)

Answer 15

curve is under the x axis and downward.. at x = 0 it peak

Answer 16

at y =0 you can find x value and at x= 0 find value of y...

Answer 17

if you had studied derivatives, this becomes way easier

Answer 18

just a little bit and thank you again all for helping
