The graph of function is shown in the -plane above. I believe there are other khan academy lessons which show this concept.
To find a point on the graph, select an input value and calculate the output value. Note: if you're graphing by hand, it's more important to recognize that the value of will grow to positive infinity as increases than getting the graph exactly right! Not only is the -intercept the easiest feature to identify, it also helps you figure out the rest of the features. Register to view this lesson.
