hi. Whenever you see a () and depending on the sign you are shifting left or right
if you see a + in the () you are moving left
if you see a - in the () you are moving right

usukidoll · Answer

() <- parenthesis

anonymous · Answer

ohh ok thank so it would be this right?

usukidoll · Answer

(x+3) means we're moving left by 3 units 
do you have the original graph with you or do you have a question that just says  "Which of the following represents the graph of f(x) = 2(x + 3)"

anonymous · Answer

no it just ask me, "Which of the following represents the graph of f(x) = 2(x + 3)" and gives me four graphs

usukidoll · Answer

ok... I only see 3 graphs attached

usukidoll · Answer

I'm missing a graph.

anonymous · Answer

here

usukidoll · Answer

ok the answer is really not that one... that's shifting up 3 units and we can't have a parenthesis

usukidoll · Answer

and it's the wrong sign too. I would've had a - for down

anonymous · Answer

oh ok so it has to be the third one?

usukidoll · Answer

I was comparing carefully between the first and this one http://assets.openstudy.com/updates/attachments/5590bce2e4b0058b2bb7418d-marcorie-1435549126870-math.gif but it seems like it's right. I'm just double checking the coordinate points.. then again anything that is shifted to the left by a lot should be right

usukidoll · Answer

blah I meant between the second and third.. 
looks like the second one is the original and there are graph shifts

usukidoll · Answer

first and fourth are out...

anonymous · Answer

ok thank you i think its the third also

usukidoll · Answer

yeah.. because the first and fourth were obviously not shifting to the left.. I see up and down

usukidoll · Answer

it was kind of hard because f(x) =2(x+3) is actually a line

anonymous · Answer

yeah when i looked it up it showed a lin.

usukidoll · Answer

ahhahaha those guys gave the wrong function XD!

anonymous · Answer

i used the same website

usukidoll · Answer

oh cool. I had to use that site once last year for Partial Differential Equations D:

anonymous · Answer

anyway thank you so much :))))

you're welcome :)
