OpenStudy (melodycrazysouthern):

@Hero @jigglypuff314 @Miracrown @TheSmartOne maby they can help you this question is confusing

OpenStudy (anonymous):

I'm working with @Hero also

TheSmartOne (thesmartone):

Why do you like to ask the question and then close it? You will get better help if you keep your post open. Also, you could get faster help if you ask one question at a time :P

TheSmartOne (thesmartone):

Have you answered any of the 5 questions you posted?

OpenStudy (anonymous):

I get confused with doing one at a time. I will try it opened next. no not yet. @TheSmartOne .

OpenStudy (anonymous):

@TheSmartOne

TheSmartOne (thesmartone):

which question?

OpenStudy (anonymous):

any one. we can start with 7

OpenStudy (anonymous):

TheSmartOne (thesmartone):

ok

TheSmartOne (thesmartone):

What do you think the answer is after looking at the graph: https://www.desmos.com/calculator/czgbcb4wfj

OpenStudy (anonymous):

i'm not sure what to to do

OpenStudy (anonymous):

is it C

TheSmartOne (thesmartone):

look at the graph once more before you choose an answer you need to see how the graph moved from \(\sf\Large y = \sqrt{x}\) to \(\sf\Large y=\sqrt{x-7}+8\)

OpenStudy (anonymous):

does it go to left or right?

OpenStudy (anonymous):

I think it is A

TheSmartOne (thesmartone):

A is correct! :)

OpenStudy (anonymous):

Can you help with this one?

TheSmartOne (thesmartone):

here's the graph https://www.desmos.com/calculator/pllikvttwi

OpenStudy (anonymous):

it a or d?

OpenStudy (anonymous):

im going withd

TheSmartOne (thesmartone):

Do you see the graph of \(\sf\Large \sqrt{x-6}+2\) move up by 2 units or down by 2 units?

OpenStudy (anonymous):

hmm

OpenStudy (anonymous):

so it is either A or C

TheSmartOne (thesmartone):

so, choose again, a or d?

OpenStudy (anonymous):

a

TheSmartOne (thesmartone):

correct :D

OpenStudy (anonymous):

TheSmartOne (thesmartone):

ok a little hint

OpenStudy (anonymous):

?

TheSmartOne (thesmartone):

hold on, I'm typing it :P

TheSmartOne (thesmartone):

whenever we have a number inside of the squareroot look if we are adding or subtracting \(\sf\LARGE \sqrt{x+y}\) for this, the graph would move to y units LEFT remember P-L-U-S means we move L-E-F-T plus is 4 letters and left is 4 letters and when we have \(\sf\LARGE \sqrt{x-y}\) , the graph moves y units to the RIGHT remember, M-I-N-U-S inside means we move R-I-G-H-T minus is 5 letters, and right is 5 letters

TheSmartOne (thesmartone):

so what is the answer?

OpenStudy (anonymous):

D?

OpenStudy (anonymous):

@TheSmartOne is that right? Can you help me with this?

TheSmartOne (thesmartone):

D is correct for the previous one

OpenStudy (anonymous):

not sure about 16

OpenStudy (anonymous):

not sure about 16
