# Major Steps of Graphing

This lesson has two major parts, easy and advanced. Whenever you need to draw a graph, you always need to follow the following guidelines.

# How to plot a nice graph with sweaty shaky hands

I have to make a terrible confession. My hands are sweaty and they shake a lot. I am generally a messy person and my wife complains that my desk is a nightmare. Maybe she is right. But my experiences taught me how to plot nice graphs.

 Take your time. I had to learn it the hard way, whenever I took a shortcut I had to spend a lot of time fixing my mistakes. Use a ruler. Use a pencil, not a pen, it is easier to erase Plot with small strokes of your pencil. Do not try to plot the entire graph in one move of your hand.

# Determining the nature of the function you are graphing

Remember that the high school curriculum is designed so that even relatively stupid students can get decent grades, provided that they spend time doing homework and read textbooks. So in most schools, you will not be asked to plot very fancy graphs.

This chapter helps you do 90% of your graphing homework by jumping to the appropriate type of graphs. For those of you who study advanced math, or are curious, more explanations are provided in the advanced sections of this lesson.

You can expect graphs of the following type:
