Exercise 11 Page 349

We are asked to graph the equation $y=|x|$ according to the given transformation. When translating absolute value functions, vertical translations occur after the absolute value has been evaluated. This is why they are outside the absolute value symbols. Consider the following general equation, where $k$ is a real number. The graph of this equation is a vertical translation of $y=|x|$ by $k$ units. Let's start with the graph of $y=|x|.$
