Making Good Graphs: Guidelines for Plotting Functions with Absolute Values, Slides of Algebra
Guidelines for creating accurate and clear graphs of functions with absolute values. It emphasizes the importance of arrows pointing in positive directions, labeling axes on positive ends, marking and labeling units, using a ruler, and labeling significant points. It also explains why it is necessary to graph both functions in the document and provides instructions for constructing the graphs using a table and connecting the dots.

Making Good Plots
1. Arrows in POSITIVE Direction Only
2. Label x & y axes on POSITIVE ends
3. Mark and label at least one unit on each axis
4. Use a ruler for Axes & Straight-Lines
5. Label significant points or quantities
Example Graph AbsVal
Need to Graph
g ( ) x = x + 2 h ( ) x = x + 2
When in
Doubt:
T-Table
x y^ =^ g^ ( x^ ) = | x^ +2|^ x y^ =^ h^ ( x^ ) = | x^ |+ -6 4 -6 8 -5 3 -5 7 -4 2 -4 6 -3 1 -3 5 -2 0 -2 4 -1 1 -1 3 0 2 0 2 1 3 1 3 2 4 2 4 3 5 3 5 4 6 4 6 5 7 5 7 6 8 6 8
Then PLOT (x, y) Points and
Connect the Dots to
Construct the Graphs
