9-3 Translations A translation is a change in the position of a figure either up, down, left, right, or diagonal. Adding or subtracting constants in the equations of functions translates the graphs of the functions.The graph of
g x ) = x 2 k translates the graph of f x ) = x2 vertically.
If k > 0, the graph of f(x) = x
2 is translated k units up.If k < 0, the graph of f(x) = x
2 is translated k | units down.The graph of
g x ) = (x - h) 2 is the graph of f(x) = x 2 translated horizontally.If h > 0, the graph of f(x) = x
2 is translated h units to the right.If h < 0, the graph of f(x) = x
2 is translated | h | units to the left.Study Guide and InterventionTransformations of Quadratic Functions
Describe how the graph of each function is related to the graph of f x ) = x 2Example
a. g(x) = x 2 + 4The value of
k is 4, and 40. Therefore,
the graph of g x ) = x 2 + 4 is a translation of the graph of f x ) = x 2 up 4 units. g(x) f x x b. g(x) = (x + 3) 2The value of
h is3, and
3 < 0. Thus, the
graph of g x ) = (x + 3) 2 is a translation of the graph of f x ) = x 2 to the left 3 units. y x O f(x) g xExercises

Dilations and Reflections A dilation is a transformation that makes the graph narrower or wider than the parent graph. A reflection flips a figure over the x - or y -axis.The graph of
f x ) = ax 2 stretches or compresses the graph of f x ) = x 2If |a| > 1, the graph of f(x) = x
