Answer:
(-2,-12), (-1,-6), (0,-3) and (1,-3/2)
Step-by-step explanation:
g(x) = -3(1/2)^x
Putting values of x
x     g(x)
-2    -3(1/2)^-2 = -12
-1     -3(1/2)^-1 = -6
0     -3(1/2)^0 = -3
1      -3(1/2)^1 = -3/2
Now, making the graph we will plot
(-2,-12), (-1,-6), (0,-3) and (1,-3/2)
The graph is shown in figure below.
