Horizontal Shifts
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A constant added inside the input shifts the graph horizontally, backward from expectation: g(x) = f(x − h) moves right by h.
Show
g(x) = (x − 2)² is x² slid right 2: the graph's lowest point sits at x = 2, where the inside zeroes.
Watch for
Minus inside means rightward; the sign lies.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
