Arrows in POSITIVE Direction Only
Label x & y axes on POSITIVE ends Only
Mark and label at least one unit on each axis
Use a ruler for Axes & Straight-Lines
Label significant points or quantities

3. Example  Graph AbsVal Observation about:
Neither of these Functions can EVER be NEGATIVE
Therefore their graphs will NEVER Extend into the BOTTOM half of the XY plane
Can NOT simply IGNORE the AbsVal Bars to Plot Lines:

4. Example  Graph AbsVal Need to Graph When in Doubt: T-Table
Then PLOT (x, y) Points and Connect the Dots to Construct the Graphs
Plot on Bd using PPT Grid
