Graph the function y = |1.6x – 2| – 3.2. Over which interval is the function increasing?

The graph changes direction where the expression inside the absolute value is zero: 1.6x − 2 = 0, so x = 1.25. The absolute-value graph is a V opening upward, so it increases to the right of its vertex. Therefore, it is increasing on (1.25, ∞), choice A.
