Question 213221
1)As a table, make a table with 2 columns and 5 rows. Label the first column "x" and the second column "y". Then use the coordinates of the given points to fill in the table.
row 1 has -2   -4
row 2 has -1 -1
and so on

2) As a graph, lay down a standard Cartesian grid (like graph paper). Then plot the 5 given points. If you see a "curve" in thyat data, then sketch in the curve

3) As mapping diagram, draw an ellipse shaped like a "0", leave an inch of two of space and then draw a second one to the right of the first (same shape, same size).
Put all of the x values in the left ellipse (see column one from the table in part 1). Put all the y values in the right ellipse (see column two from the table above).
Now connect the x values in the left ellipse with the corresponding y values in the roght ellipse. Just draw a line from one to the other. That is the "map"
