#### Topic: Introduction Tutorial?

I just download and installed this product. I have a very basic knowledge of Calculus and have started a review of material from my courses. I am having great difficulty graphing functions. I have been able to graph a linear function as two functions one using Dots and another using Lines producing the correct straight line graph. Is this normal practice? Creating two functions one to show points and another to show the line? I have had no luck getting other graphs, such as any power functions. Sometimes dots show, but no lines.

I have read the manual but it provides no examples. Can someone walk me through the process of entering power functions and getting a graph for them? Are there any tutorials available?
