Question

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

(1.25, ∞)
(3.25, ∞)
(–∞, 1.25)
(–∞, 3.25)

Answer 1

Answer:

The interval over which the function is increasing is:

                (1.25,∞)

Step-by-step explanation:

We are given a modulus function by:

        $y=|1.6x-2|-3.2$

From the graph of the function we see that the function is first decreasing in the interval (-∞,1.25) and then it increases continuously in the interval (1.25,∞) and goes to infinity.

     Hence, the answer is:

                   (1.25, ∞)
