Question

Write an algebraic equation to match each graph. (These graphs are not drawn to scale!)

Answer 1

y = |x - 1|

Explanation:

This graph is the standard graph of y = |x|, shifted 1 unit right. To shift 1 unit right, we have to replace x by x - 1. This works because it replaces f(1) with f(0), f(2) with f(1), etc., shifting the entire graph right.
