Answer 2

ERR

Start with y = sqrt (x)
as h = -2, sub y with y - h, ie y + 2
as k = 4, sub x with x -k , ie x -4

Thus you'll get

y+2 = sqrt (x-4)

Answer 3

ERR

Start with y = sqrt (x)
as h = -2, sub y with y - h, ie y + 2 ===> graph is shifted two spaces up
as k = 4, sub x with x -k , ie x -4 ===> graph is shift 4 spaces right

Thus you'll get

y+2 = sqrt (x-4)

Answer 4

thanks mate! @dauspex
