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

Page 2: Example of a wrong problem

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).
