Horizontal Shifts

The idea
A constant added inside the input shifts the graph horizontally, backward from expectation: g(x) = f(x − h) moves right by h.
In practice
g(x) = (x − 2)² is x² slid right 2: the graph's lowest point sits at x = 2, where the inside zeroes.
Where people slip
Minus inside means rightward; the sign lies.
