@kirbykirby I got C

OpenStudy (anonymous):

OpenStudy (kirbykirby):

the absolute function has the general form: \(y = a|x-h|+k\) here, \(h\) means a translation to the left or right \(k\) means a translation going up or down. and the signs: (-) is when moving left or down (+) is when moving right or up

OpenStudy (anonymous):

I got C..

OpenStudy (kirbykirby):

This is a bit "tricky" because here, there is already a minus in front of the h. So if the graph is going to the left by 1, then \(h = -1\) so: \(y = |x-(-1)| = |x+1|\)

OpenStudy (anonymous):

WEll I'm stuck between C and D. Based on your explanation, it has to be =+2 ; so it's either B or C..

OpenStudy (kirbykirby):

Yes between B and C. But ya it looks confusing to see |x+1| meaning a shift to the left, but that's because the basic form of the function has the form |x - h|

OpenStudy (anonymous):

is it |x--1| ? If so then the it becomes |x+1|

OpenStudy (kirbykirby):

yes

OpenStudy (anonymous):

then*, no it... so it's b. because 2 negatives make a pos. |x+1| , therefore it can't be c. because it has |x-1| <- unless that's what you meant?

OpenStudy (kirbykirby):

no no it's B :) because of the 2 negatives

OpenStudy (anonymous):

Thank you; have a great day! :D

OpenStudy (kirbykirby):

Oh dear I gotta run!! good luck with the rest of the problems :)

OpenStudy (kirbykirby):
