Sketch a Function by Hand
1.
Graph the following function by hand.
Write the input-output values as ordered
pairs. Then, draw your graph.
You can do this in one of three ways:
●
Use a sheet of graph paper or the graph paper below, a pencil, and a ruler to
sketch your graph. Insert an image of your hand-drawn graph in your work.
●
Use the Scribble tool or other drawing tools in your word processing
application to draw the graph.
●
Use the ACCESS Manual Graphing – Blank Grid to create your graph.
