This function is shown on A and IV

#### Work Step by Step

The graph of this function is on the graphs A and IV. Namely, we see that this function oscillates only along the $y$ axis, while its amplitude increases along the $x$ axis. This is also seen on the graph IV -- the periodicity in the $y$ direction is easily seen, while as $x$ increases, so does the density of the level curves because the rate of change is more intense (the function oscillates with the same period but with greater amplitude so it changes more in value).
