Example of a wrong problem.
This is an incorrect graph.
The bottom line should be a closed dot and it is at the wrong (x,y) point. Also the graph is not going through the correct data points.
Corrections:
2x - 3 when x > 0 A) closed dot (state why).B) dot is at (0, -3)
Now re-sketch the entire graph and do it correctly.
x y
0 -31 -12 13 3
Corrected problem (example)
2x - 3 when x > 0 A) closed dot (state why).B) dot is at (0, -3)
x y
0 -31 -12 13 3
Examples for WS Corrections.
This is the correct graph.
If there is a mark on the dot, then you either missed open/closed dot (correction A) or the circle is correct but the (x,y) coordinates are wrong (correction B).
If the word dots is written on the problem, or if a line is circled, then you need more dots to get a more accurate graph. List a table of data for points on the graph (list at least 3 data points).
If an x is drawn on a piece of your graph, then you have the wrong shape or erased the wrong side (correction D).
