Translations f(x) = (x – h) + k + h moves graph left - h moves graph right + k moves graph up - k moves graph down

This Relationship… Holds true for the graphs of all other functions, such as absolute value and square root, as well.

Parent Graphs These parent graphs are ANCHORED at the ORIGIN (0, 0).

Key Points: (-2, 4) (-1, 1) (0, 0) (1, 1) (2, 4) Key Points: (0, 0) (1, 1) (4, 2) Key Points: (-2, -2) (-1, -1) (0, 0) (1, 1) (2, 2)
