    You have four sections left is negative and down is negative while up and right are positive

    \[\rm f(x-h)\] here h is horizontal shift f(x) + k here k is vertical shift \[\huge\rm y =\left| x-h \right|+k\] if h is negative graph will shift h unit to the right if h is positive graph will shift h unit to the left if k is positive graph shift k unit p if k is negative some unit down

    If y = x-2 then the x intercept would be at x = 2 y = 0 , hence moving the graph to the right. If y = x + 2 , the x intercept would be at x = -2 , y = 0 , therefore moving to the left. You can graph it out to see the difference. c:

    if h is positive then graph shift to the `left` side if h is negative then graph shifts to the `right` side

    i didn't say it's not A ,B C or D :=) according the information which one do you think it's ? i repeat if he is negative then graph shift to the right side if it's positive then graph shift to the left side |dw:1444244253550:dw|

    there isn't any number outside the bar so pretty obvious it can't go up or down :=)

    Because +h has to go to the left!

    but it's \[y = \left| x\color{Red}{-} 2 \right|\]

    Ohh so it's negative! That means it goes to the right, so it is C!
