I think C is the closest.

OpenStudy (anonymous):

my graph looks kinda different from the picture I have so idk which one is which.

jimthompson5910 (jim_thompson5910):

hint: look at a known point on the graph, say (4,3) the idea is that if you plug in x = 4, you should get y = 3 (or close to it)

OpenStudy (anonymous):

well maybe what she thought was right wasn't. Anyways I appreciate people going back and redoing thinks if they think they did something wrong.

OpenStudy (anonymous):

@jim_thompson5910 plugging in x x=4 and it did give me y=3

jimthompson5910 (jim_thompson5910):

which equation did you plug into?

OpenStudy (anonymous):

um y= 1/3 x^2 -x + 2

jimthompson5910 (jim_thompson5910):

you should get 3.3333... which is pretty close enough. Double check your calculations again

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

for C I plugged in the values and got y=6 so I don't think it's that one.

jimthompson5910 (jim_thompson5910):

yeah C is way too high, so that's out

OpenStudy (anonymous):

yep checked again and I got 3.3333

jimthompson5910 (jim_thompson5910):

how about A and B?

OpenStudy (anonymous):

let me see...

OpenStudy (anonymous):

for A I have y = -2/3 ... I think and for B = -14

OpenStudy (anonymous):

@jim_thompson5910

jimthompson5910 (jim_thompson5910):

I'm getting the same. So those are way off as well. Leaving D as the only answer

OpenStudy (anonymous):

yeah thank you. Now I know how I can check my answers now :)
