help a closed question with no question now I am confused!

OpenStudy (here_to_help15):

OpenStudy (triciaal):

what do you need to do to move from point A to point A' hint you are on the same Y level only the X value has changed

OpenStudy (here_to_help15):

Hmm I thought it was B am i wrong?

OpenStudy (triciaal):

to go from B to B' what do you need to do?

OpenStudy (here_to_help15):

wait what??

OpenStudy (here_to_help15):

woah woah woah i mean x and y

OpenStudy (triciaal):

I think the question wants to know what function will apply to both situations

OpenStudy (triciaal):

option 1 actually works for both situations

OpenStudy (triciaal):

first we agree that the value for y remains the same

OpenStudy (triciaal):

x + 7 to move A to A' only x + 3 to move B to B' only

OpenStudy (here_to_help15):

Hm ok i get what your saying

OpenStudy (here_to_help15):

OpenStudy (here_to_help15):

Can we try this one if your not too busy?

OpenStudy (triciaal):

other approach use the coordinates A(-4. -2) go to (3,-2) look at the x values x goes to -x then -1 -4 goes to -(-4) then -1 apply this to the Bs B (-2, 2) goes to -(-2) then -1 the Y values remain the same so the function of transformation is (x,y) goes to (-x -1, y)

OpenStudy (triciaal):

y went down 4

OpenStudy (here_to_help15):

Oh ok

OpenStudy (triciaal):

x reflected across the y axis x-value now -x value notice D on the opposite side?

OpenStudy (triciaal):

B = 0 so still on the 0-line

OpenStudy (triciaal):

hope that helped have to go

OpenStudy (here_to_help15):

I believe its A or D right?

@dtan @Nnesha

@dtan5457

OpenStudy (alexandervonhumboldt2):

so no it is (x, y) => (x+3, y) and (x, y) => (x+7, y)

OpenStudy (here_to_help15):

I am done with the first question @AlexandervonHumboldt2
