1. The problem statement, all variables and given/known data Could someone please explain, in very simple words, the horizontal shift of a graph? I've used the search button, textbooks, and google and I'm just not comprehending this. Why does the graph f(x-1) shift f(x) 1 unit to the right and not left? 2. Relevant equations f(x) = x Let's keep it simple. 3. The attempt at a solution If I take some ordered pairs, say (0,0), (1, 1), (2,2) as points on f(x), then try to create the new ordered pairs with f(x-1), shouldn't they be (-1, 0), (0, 1) (1,2) and the f(x-1) graph be moved 1 unit to the left?
