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

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

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
2 is stretched vertically. If 0 |a| < 1, the graph of f(x) = x 2 is compressed vertically.The graph of the function
f x ) ? ips the graph of f x ) = x 2 across the x -axis.The graph of the function
f x ) ? ips the graph of f x ) = x 2 across the y -axis. Describe how the graph of each function is related to the graph of f x ) = x 29-3Study Guide and Intervention (continued)

x0 < a < 1
a = 1 a > 1 xy O f x x 2 f x x 2Example
a. g(x) = 2x 2The function can be written as
f x ) = ax 2 where a = 2. Because |a| > 1, the graph of y = 2x 2 is the graph of y = x 2 that is stretched vertically.b. g(x) = - 1 2 x 2 - 3The negative sign causes a reflection
across the x -axis. Then a dilation occurs in which a 1 2 and a translation in which k = -3. So the graph of g(x) = - 1 2 x 2 - 3 is reflected across the x -axis, dilated wider than the graph of f x ) = x 2 , and translated down 3 units.Exercises
