To describe the transformation of the function [tex]\( f(x) = |x| \)[/tex] to the function [tex]\( g(x) = |x + 2| + 4 \)[/tex], we need to perform the following steps:
1. Shift Left: The term [tex]\( |x + 2| \)[/tex] indicates that the function [tex]\( f(x) = |x| \)[/tex] is shifted to the left by 2 units. This is because adding 2 inside the absolute value function [tex]\( f(x) \)[/tex] translates the graph horizontally in the negative direction.
2. Shift Up: The term [tex]\( + 4 \)[/tex] outside the absolute value function indicates that the entire graph is shifted upward by 4 units. This vertical shift is added to the output of the function [tex]\( |x + 2| \)[/tex].
Therefore, to obtain the function [tex]\( g(x) \)[/tex] from [tex]\( f(x) \)[/tex], we do the following transformations:
- Shift [tex]\( f \)[/tex] to the left by 2 units.
- Shift [tex]\( f \)[/tex] up by 4 units.
So, to complete the description in the question:
To get the function [tex]\( g \)[/tex], shift [tex]\( f \)[/tex] up/down 4 units and to the right/left by 2 units.
This perfectly describes the transformation required.
