@satellite73 can you help me please Ive been stuck for an hour

OpenStudy (jkbo):

@dumbcow can you please help me?

OpenStudy (anonymous):

what's the transformation?

OpenStudy (jkbo):

I'm not sure I just learned this @pgpilot326

OpenStudy (anonymous):

you're giving incomplete info

OpenStudy (jkbo):

I have a graph in the attachments

OpenStudy (anonymous):

yes, i know. you still haven't given all of the info needed. P is at (-2, 4) and Q is at (1, 7). None of the answers match and they're given in terms of P' and Q' which are generally points which have been transformed from some original position.

OpenStudy (jkbo):

I'm sorry but these are the only answer choices I have, But it does look pretty weird thats why I asked the question on here. P'(0, 4), Q'(–1, 7) P'(-1, 4), Q'(–3, 7) P'(0, 4), Q'(–3, 7) P'(-1, 4), Q'(1, 7)

@pgpilot326

OpenStudy (anonymous):

what's the question being asked?

OpenStudy (jkbo):

Identify the points corresponding to P and Q.

OpenStudy (anonymous):

and that's all that's given? nothing about a rotation or translation of any kind?

OpenStudy (jkbo):

Nope just that, my closest guess is that its D.

OpenStudy (jkbo):

But Im really not sure

OpenStudy (anonymous):

good luck. something is goofed.

OpenStudy (jkbo):

Can you help me with one simliar to this one? please @pgpilot326

OpenStudy (anonymous):

what is it?

OpenStudy (jkbo):

Which of the following equations describes the graph?

OpenStudy (jkbo):

A.y=-1/2x^2-x-2 B.y=1/3x^2-x-2 C.y=1/2x^2-x+2 D.y=-1/3x^2-x+2

OpenStudy (anonymous):

look at the graph... when x = 0, y is 2 so it can't be either of the first 2 choices. next, when x = 3, y = 2. Plug in x = 3 to the remaining equations and see which one works.

OpenStudy (jkbo):

o ok so the answer is C.

OpenStudy (anonymous):

you didin't do the work

OpenStudy (jkbo):

yes I did on my sheet of paper

OpenStudy (anonymous):

so \[\frac{ 1 }{ 2 }\left( 3 \right)^{2}-\left( 3 \right)= 0?\]

OpenStudy (jkbo):

i got -2.9

OpenStudy (anonymous):

exactly... but the result needs to be 0 which is why C is not the answer. Try it with D and see what you get.

OpenStudy (jkbo):

it was D. it equals 0

OpenStudy (jkbo):

Thank you very much

you're welcome
