Write an algebraic equation to match this graph.

Using translation concepts, the algebraic equation that matches the graph is given by:
y = |x - 1| - 1
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the function y = |x| is:
Thus the algebraic equation that matches the graph is given by:
y = |x - 1| - 1
