Let's start with finding the y-intercept. When x is equal to 0, we know that the graph is crossing the y-axis. So, when we have x be 0 in the equation:

It looks like the y-intercept is at y = 0.

Now let's find the x-intercept. When y is equal to 0, we know that the graph is crossing the x-axis. So, when we have y be 0 in the equation:

It looks like the x-intercept is at x = 0.

Now let's look for the asymptotes. An asymptote happens when the value of y is undefined. The easiest way to find an asymptote is for the bottom of the fraction to equal 0. In this case:

Because the answer to this isn't a real number, there are no asymptotes.
