Question

Algebra Help Please? O-O Thank you!

Answer 1

Graph the Function y=3x^2 . Draw a chart to show at least three ordered pairs that are on the graph.

Answer 2

have you found your 3 ordered pairs you want to use?

Answer 3

Does it matter what they are or are they just any numbers?

Answer 4

Thanks so much for helping me btw :D

Answer 5

To get a better idea of what your graph looks like I suggest using a negative, a neutral, and then a positive input.

Answer 6

Ok so would (-2,-3) (0,-3) and (1,0) Work? o.o

Answer 7

I don't know how you got any of those points. :(

Answer 8

so if x=-2, then y=3(-2)^2

Answer 9

and if x=0 then y=3(0)^2
and if x=1 then y=3(1)^2

Answer 10

Lol sorry im so bad at math xD

Answer 11

So what points should i use then

Answer 12

you get to choose the inputs of the ordered pairs

Answer 13

I suggested some inputs above

Answer 14

A true scale plot is attached.

Answer 15

if x=-3 then y=?
if x=0 then y=?
if x=3 then y=?

and remember y=3x^2

Answer 16

one second brb

Answer 17

So i put in -3. So 3*-3^2=-27 ?

Answer 18

@freckles

Answer 19

not exactly

Answer 20

3x^2
means the same thing as 3*x*x

Answer 21

so if you input -3
then y=3*x*x=3(-3)(-3)=positive 27 not negative

Answer 22

Oh ok .
