Horizontal Shift of Functions Explanation NOBODY Explains
A horizontal shift of a function occurs when a constant is added or subtracted within the input location (where you enter your values into your variable on the right hand side of a function).
The rules for how much you shift a function horizontally and the direction you shift a function sometimes feel out of thin air.
This video attempts to provide some context for the rules that students normally commit to memory for horizontal shifts.
