Question 149064
make your own table of values for the function y=(-2)^x . Use the integers from -3 to +3 for your x values. Graph these points on a sheet of scrap paper. What happens to your graph? What are your coordinates for the table and your thoughts about the graph with the assignment.
:
Use a calc for each value of x and find y
for x = -3; enter (-2)^-3 = -.125, note that the bracket is important here.
the table
 x | y
-------
-3 |-.125
:
Do the same with x = -2: enter (-2)^-2 = +.25
 x | y
-------
-3 |-.125
-2 |+.25
Continue with x values, -1, 0, 1, 2, 3, the table should look like this
x | y
-------
-3 |-.125
-2 |+.25
-1 |-.5
 0 |+1
+1 |-2
+2 |+4
+3 |-8
:
Note the graph will consist of these points only, If you enter a non-integer value for x, you get an error.
NOte that even values for x, y is positive, odd values, y is negative
