# Functions Translations and Reflections

Translations of graphs:
Translate a graph m (m > 0) units to the right, by replacing x with x - m.
Translate a graph m (m > 0) units to the left, by replacing x with x + m.
Translate a graph m (m > 0) units up, by replacing y with y - m.
Translate a graph m (m > 0) units down, by replacing y with y + m.

Reflections of graphs:
Reflect a graph in the y axis by replacing x with -x.
Reflect a graph in the x axis by replacing y with -y.
Reflect a graph in the x = y line by replacing x with y and y with x.

2. Given f(x) = x2 + 5x, what is the equation of the function g(x), if the graph of g(x) is found by shifting the graph of f(x) 1 unit left?

3. Given f(x) = x3, what is the equation of the function g(x), if the graph of g(x) is found by shifting the graph of f(x) 2 units left and 3 units down?
