A General Note: Combining Transformations
Horizontal and vertical transformations are independent. It does not matter whether horizontal or vertical transformations are performed first.
Does the order of function transformations matter?
The order does not matter. Algebraically we have y=12f(x3). Of our four transformations, (1) and (3) are in the x direction while (2) and (4) are in the y direction. The order matters whenever we combine a stretch and a translation in the same direction.
What is the rule for the transformation?
The function translation / transformation rules: f (x) + b shifts the function b units upward. f (x) – b shifts the function b units downward. f (x + b) shifts the function b units to the left.
