Exercise 12 Page 547

Consider the given function for the velocity $v$ of a tsunami. Let's graph this function in our graphing calculator! We begin by pressing $\boxed{Y=}$ and typing the function. Before we push $\boxed{\text{GRAPH}},$ we will change the window settings in order to take a better look at the graph. This can be done by pressing $\boxed{\text{WINDOW}}$ and typing the window settings.
