See solution below.

Explanation:

It's important to plot a couple of points first. That is, select reasonable x values for inputs and calculate the corresponding y values. Putting them in a table like this makes it easier to draw the graph.

Next, plug these points x-values (moving left or right along the horizontal axis) and y-values (moving up or down along the vertical axis). Here is what you get.
